very nice trigger handling

Tq... but, not that good la. I need to pull the trigger and release it quickly. The spindle keep spinning due to the inertia, and it tighten the screw.

I still can pull the trigger delicately enough NOT to invoke the impact mechanism, and stop accordingly, just like what the powered screw driver.

But, we are human and we may make mistakes... That's why, an advanced impact driver has several modes to suit the needs. No need to say, it's cost.....

Added on May 21, 2012, 1:27 pmYes, threre are more appropriate power tools for this task. The Makita DF030 or simalar drill driver with CLUTCH, which limits the torque accordingly, preventing any damages.
We can still use the impact driver for delicate tasks, but use the varible speed control trigger wiesely.. If you don't any confident, don't use impact driver, and use the drill driver instead or,... hand tools such as the screw driver.

The electronic appliance, Sony DPS M7 which I showed has 15 screws, and twisting the screw driver is quite tiresome for 'old' person like me. Beside the appliance, I also use the impact driver to dissamble front loading washing machine, and has .... many screws to deal with.

Saw somewhere that Dewalt came out with an acessory that serves like a clutch but in a bit form for impact drivers. This tool can save bits from breaking. So by using this accessory the impact driver behaves like a drill driver with clutch. The only thing is that its not a variable clutch.

Dewalt impact clutch holder.


If you are using impact driver all day long, I quite sure your finger 'knows' how much tu pull the trigger. Also , using good screw driver bit, such as the Makita Torsion screw driver bit, we may reducing the risk of damaging the screw and the bit itself. Since I use the bit, I don't have any ripped off screw head yet. , but YMMV.

Another interesting screw dirver bit/acceserories is Wera Impaktor.

Note: Dewalt impact clutch is NOT using the torsion technology.

Just get what JinXXX have. Combo set with drill and impact. Can cover every expect of drilling. Good price too.

I already have the impact driver. , and it did excellently in any tasks. No need of the drill driver for now, yet.


Let's see what JinXXX opinions about drill driver (DF030) and the impac driver (TD090).

Thank you.

Just like me. I already have the bosch corless screw drill with torque selector. Good for drilling and screwdriver. No need impact type.

JinXXX set very tempting for the whole package.

Impact driver is best for fasten ing/screwing but, also can drills too. So no need for drill driver. heh eh he.
+1, Definitely tempting.

My last project (UPSI Tg Malim) I had the oppurtunity to tryout the latest cordless tools offered and finally opted for Dewalt. We bought 2 sets of the combo pack consisted of the impact and drill driver. What I have noticed is that, the impact driver fare very well in installing roofing deck, hoardings, drywalls and plaster ceiling. Feedback from my workers also they prefer the impact to the drill driver as it is smaller, and less stress to the hands and can be used all day long.
The only concern was bits. By using impacts, the bits dont last that long. Also the quality of the screws used is also important. Chewed screw heads is already a headach but a broken screw due to shear is worst and happens alot when using impact drivers. Probably its more workers error than anythng else but this type of issues do crop up.
Nonetheless, for drivng self taping screws into metal decks or into treated wood, impacts are far superior.

Thank you for the very valuable information, from the real builders. Yes, we need to use a good quality bits which can wit stands the torque. In my case a hih quality screw driver bit which claims 10x tougher than normal bit also can break in less than 20 times driving 3" screws. No wonders, they are selling bits in large quantity.

seems like its quite pricey.. or maybe worth it depending on how you see it

bahathir u got a screwdriver bit that is quite long and the middle quite "thin" that you recently bought, where did u get that from ?

seems like the screws last longer than the bits lol

yeah seen those bits pack at ace.. 10 bits x 2 head (opposite sides) for like 40 bux lol

I got the 85mm Makita Torsion Screw driver bit as a sample from a distributor, before the 3x 110mm torsion screw driver bit which I ordered arrives. Contact/PM our Makita friend. The 85mm version is available during the last Makita roadshow @Kepong and cost less than MYR50. I was told that the torsion bit had being used for demo at the roadshow, was being used for years! and the tip(s) still in very good condition. Imagine how many screws had been driven by that bit. Mine already drove screws for about 100 times and still in excellent shape. Yeah, might be my DIY environment is not as hard as the real construction's site.


Yes, those bits at AceHW and Living Depot or other HW stores. If you are want to drive thousands of screws for projects, MYR40 is not that burdening. .

any idea when the new makita roadshow will be coming ?

does bosch have some kind of torsion bit also ?

My personal experience is that the best power-tool for driving screw is BN. They have been screwing Malaysians non-stop for the past 50 years...

Hah ah hah ahh a... but, at least, we able to freely disusing about screwing here.



JinXXX
I am not sure. AFAIK, Hitachi, Dewalt, Wera and Makita have torsion bit.

Yup free to discuss, but NOT FREE AFTER discuss! That's another Malaysia's specialty.

OT:
But, still better than North Korea or China or other countries where you will be caught and killed, just because of a discussion. At least our country is in peace, not like other countries.

well for those that planning to get an impact driver can consider this

http://www.lelong.com.my/bosch-cordless-im...3-05-Sale-P.htm

Model: GDR10.8-Li & GSR10.8-2-Li (Included Battery x 2, Charger)
MYR 620.. quite worth it

Bought myself GSR10.8-2-Li.. So convinient and reliable.. No regrets..

Makita will have roadshow outstation in K.Terengganu at 3 - 7th June. While local Klang Valley falls on 14th - 16th Kepong.

Atm, Makita torsion bit available stock are 85mm and 150mm. And 110mm stock is coming soon.
