Sorry for the typo...

Yup... 2 1/2 minutes of exhaustive twisting. I can do the fast forward, but I really want the show the real thing and why I choose power tools.

Imagine how hard to screw driving with hand tools. Actually, I already drove several time with hand tools, before taking the video. BTW, most of the my screw driving were for wall anchoring, ie, screwing into wall plugs. That were much easier than what were in the video.

Yes, ratchet driver is for small place and limited spaces, where we cannot use longer screwdriver.

Actually, I also have a ratchet screwdriver, but the handle diameter is smaller than the screwdriver in the video. I tried that also, and did not give a better result.

The problem with handtools is to keep the screwdriver at the screw's slot firmly, especially when we want to give extra torque/twist. It tend to move and slips, which may damaging the screw's head or the screwdriver's tip. The cheap screwdriver's tip is easier to be damaged and useless in no time.

Sorry for the delays... Here is the picture of the antenna mounted in the roof's attic.
I am using PVC pipe as the pole/mast. Easy to cut to the length I wanted.

Added on March 4, 2012, 5:29 pmBut, the cheap one from MYR2 shops also has the 'black' colored tip, and not as good as a branded one. . I have several occasions when I really really need to drive screws, but the the screwdriver's tip was damaged, and really made me frustrated. Even a simple handtools also need to be good in quality.

So, if you want to use it for long time, get a better branded one from hardware shop.

Yes, the impact driver has variable speed control trigger. Start with slow speed and practice using it for better control. I also using my impact driver to remove computer parts, electric fan and washing machine's screws. Most of the time, it did not engaged the 'impact' mechanism at all

The cordless screwdriver, Bosch iXO which I was using in the video does not have any speed control.

Faster spin -> higher impact rate -> more torque.

+1. I also had a pliers and set of precision screw drivers which I bought when I was in Japan, and were long lasting until they were lost ...

Beside the tool's quality, using it appropriately also can make things last longer. Always use the correct tools.

LOL... at least we learned something... ha ah ah a... The Japanese made tools are stronger then our head. heh eh heh e..

Yes, Japanese are very strict when working in factories or construction sites. They don't want anything happen which may cause tool to damage, injuries or death. That's why if you read any branded power tool's manual, 70% of pages are about safety. and correct ways to use the tool.

In Japanese factories and construction sites, you will always see this slogan
安全第一
Anzen Dai Ichi.
which means, "Safety First"

Here in Malaysia, .. IMHO, I can say お金第一 (Okane DaiIchi).. which means... Money First. See at your nearest construction sites, how many workers are using safety harness? or at least crash helmet ? The safety guides are already there, but.... who read and follows those guides?

I hope we all can spend some time to read the power tool's manual, understand and follow it. Buy a good leather gloves, safet glasses/goggles, appropriate clothing and shoes while using the power tools.

Thank you.

Thank you for the suggestion. Actually, I tried to drive the screw as FAST as possible, and the result is, what you can see in the video. Freestyle twisting.. I can put enough torque, but cannot twist quicker with the mini ratchet. Another feature of the mini ratchet is, it also come with hex socket wrenches. Next time, I may put some pictures how to use socket wrenches using impact driver and mini ratchet. It is nice small tool which I can carry along outdoor.

If you want to buy Makita TD090DWE, try contact the sole distributer, Jasakita Berhad, and ask them the nearest reseller which selling that model. I contacted them, before I bought my rotary hammer.

http://jasakita.com.my/


I found this comparison video, Makita TD0100 vs TD090DW, corded 100Nm vs cordless 90Nm. A newer cordless brushless impact driver, BTD14x series are more powerful, 140-165Nm, but, ... expensive and, you are very lucky if you found one in Malaysia.



TQ

Another type of impact driver, the soft impact driver.
The model, Makita 6963SPK Japan only model, and I really wish I can try one. The torque is only 30Nm, but enough for most screw driving tasks.

Yes, corded drill is not recommended for screw driving, because it is difficult to control power. Corded drill only produce torque when we put more power to it. Once it's start spinning, and slipping from screw head, it tend to spin at high speed and damaging the screw head, or screw bit.

Corded or cordless Impact driver is design for screw driving. When the impact mechanism is engaged, you can see it spin slowly, but maintaining the motor speed/rpm. It is like engaging low gear. This make screw driving very controllable and efficient. IMHO, I feel very confident using the impact driver.

In the video, the the small Bosch iXO cordless screwdriver spins much slower than the impact driver, but, if you look carefully, it slipped TWICE while driving the screw. So, slower speed doesn't mean it can drive screw efficiently.

Thank you.

Agreed. use correct size of the screw bit. Typically, Phillips #2 is the most common size. I said it is difficult to control the drill power, but, if you already using it for long time, you able to manage to control the power as you like. Yeah, the main problem is the weight. I already tried screw driving with 3kg rotary hammer, and it is not as pleasant as using impact driver.

Screw head broke/patah ? heh ehh e.. I already broke several screw's heads and the tips of 2 high quality screw bits. I need to control my anxiety and adrenalin, for not over using the impact driver. That's what we call experience.

Absolutely correct! Anyway, it is becomes experience. Sometime, I like to see how hard it can go, and later we can control it I may make another video, to see how it's look like, if I am not using the full power all the time.

I tend to use my tools at the max and as fast as possible, while making video clips. So something may breaks is not uprising. It doesn't reflect the way I am using for my DIY or home fixings. Example, I only use 1/2 of max power of my rotary hammer when drilling into my house's wall and take it easy.

So everyone should try or practice to use the power tools, and learn how it react.It is not hard todo, spend about an hour drilling into concrete block or driving screws into wood block. At the same time, you can check your tool's condition.

Thank you.

Yeah... the carbon brushes failure..

Today's impact drivers are using brushless motor which reducce the risk of that particular failure.

In previous page, I showed a soft impact driver, using oil damping, but, this one is much advanced... 100 % electronic control for torque and impact.

BTW, it sound similar to oil damping soft impact driver.

Added on March 5, 2012, 4:57 pmI only can see and admire the electronic pulse impact driver, Hitachi WM18D... The price is 74000 yen, or about MYR 2750 .... Wow..... The price for technology.

I bought it at Ace hardware@Mines. I found it at 'sprit level' rack.
The model number is Sellery 11-227. Mini ratchet handle with 17 pieces bits.

I googled the product, but I only found the model WITHOUT the socket wrenches.

Torque.
If you not confident about overtightened screws, you can always use normal screwdriver and tight with your hand. At least, you already save lots of time driving the screw with power tools.

For wood, just drive the screw until it flush to the surface. For machine screw or bolt, it a bit difficult to tighten at certain torque, because impact driver can deliver enormous torque without twisting your hand, like normal power drill driver. Yeah, This is a downside of the impact driver, because we cannot 'feel' the torque accurately.

BTW, even we can use normal screwdriver/wrench to tighten the bolt/screw, but, it is still not precise... For the purpose, we can use torque wrench.

TQ

Added on March 6, 2012, 1:32 pmHow about the video clip on post #2 in the first page. TD100D vs BTD141.
100Nm corded impact drill vs 140Nm cordless impact driver ?

Even a small cordless impact driver has more than 100Nm of torque, and it being used by many professionals, DIYers, ... If this type of tool has many problems, why the torque is getting higher and higher ..

How about this... Makita TD147 .. the shortest and the most powerful cordless impact driver. 170Nm! More than enough torque to remove and screw the car's wheel nuts.

http://www.makita.co.jp/product/category/a...47d/td147d.html
(In Japanese)

It is 70Nm more torque than the corded impact driver..

Again, why more torque, just for screw driving?

This post has been edited by bahathir: Mar 6 2012, 01:32 PM

More power to goes wrong. That's why high end super torque impact drivver has speed and torque selector. So it is safe for people who knows how to use it

Yes, there are correct tools for certain tasks. I also might using the Dremel multitool with some of the attachements.

http://www.dremel.com/en-us/Attachments/Pa...es.aspx?catid=9

It about conveniences and efficiency doing the tasks, what I demonstrated in the video clips. I can drive screw using screwdriver, ratchet handle, cordless screwdriver, impact driver and rotary hammer. For certain cases, impact driver is the best, and other cases, the screwdriver is the best tool. In most cases the impact driver is my choice for screw driving.

Beside screw bits, I also get free drill bits set for wood and steel drilling up to 6mm, which is enough for most of my DIY tasks. I also bought several type of screw's head bits and nut setter. The 4 mm (5/32") hex (alen key) bit is very useful when to assemble cabinets or re-tighten alen key screw which being used in most of the furnitures in my house. I also have hex -> socket adapter, and convert the impact driver into a low class impact wrench, which can use as socket wrench up to 12mm. Here, I extend the usability of the impact driver with accessories, relevant to my usage.

To further extend the impact driver capabilities, I also tried to make a small grass cutter,by tighten 2 cable tighter to the long screw driver bit. Yeah, it works,...., for several seconds heh eh e.. Yeah, the cable tighter material is not strong enough to withstand the force hitting the grasses. Mmm... I can try to use metal blade,, but.. it is just too dangerous.


IMHO my impact driver also a 'limited' multi tool.

Want to see another usage of power tools ?

Yes, the motor spin backward a bit, if the it's detects the screw bit is stopped, and start spinning forward again, the momentum creates the 'extra' torque. The man torque of 33Nm is not as much as 170Nm of the normal impact driver, but enough for most of the DIY's screw driving. But see how quick and silence it can drive screw. Since it is fully electronic control, it has very low wear and tear, but, once the electronic parts damaged,.... it is just a MYR2750 paperweight. .. Still loving my cheap corded impact driver. heh eh e.

Correct, but, we cannot get anything from 0 RPM (no spinning) ... The motor must spin to be useful.

DId you tried to call the phone number at the bottom of the main page? Sometime, we get more by calling the number, than just browsing the web pages.

OK, I sent them an email...and hope something good is coming up.
