## Description

Product description Cobalt Steel Metric M3 Combination Tap and Drill Bit Keep the drill bit vertical to the surface of the workpiece and ensure that the workpiece is securely fixed. Always wear work gloves, safety goggles and protective clothing while doing any drilling job. Drill and tap on stainless steel plate in one step Combination drill and tap bit is a good choice for on-site tapping construction, maintenance and repair, assembly and production environments. This high-quality cobalt steel combo bit is able to drill the hole and taps the threads in a single drill. The tap bit is constructed of premium material, M35 grade cobalt high-speed steel (5% HSS-Co). The TiAlN coating provides exceptional oxidation resistance and extreme hardness. This combination tap drill bit is ideal for threading on various metals like mild steel, copper, brass, aluminum alloy, cast iron, galvanized pipe, mold Steel, titanium alloy, stainless steel. 118 Degree Split Point The self-centering split point provides excellent drilling precision and accuracy. Twist Flutes Improve the efficiency to remove chips and heat and prolong the tool life. 1/4" Hex Shank Compatible with impact drill and allows for quick release to save your time. Technical Specifications Instructions Start from the lowest RPM and adjust it high slowly. Once the bit can get into the workpiece, the adjustment should be stopped. Use with cooling liquid for prolonged tool life. If you use a hand drill, the power should be 500W at least. It’s highly recommended that the combination drill and tap bit is used on a tapping/threading machine or drill press for hard/thick metal plates. If you apply an electric hand drilling machine to do the tapping job, please pay attention to your operating, because excessive shaking and tilting may affect the result and even break the bit.

Review: Worked great! - I used this combo bit to drill and tap a hole in the dropout of an aluminum mountain bike for a disc brake conversion bracket. Once I made the mark of where the center of the hole would be, I center punched it and started off with some cutting oil and a small drill bit for a pilot hole. I then switched to a slightly larger size drill bit to further widen the hole. Finally, using the combo bit in a cordless clutch power drill and some cutting oil, I slowly drilled and tapped the hole. To prevent damage to the threads when reversing out, I un-chucked the bit from the drill and reversed it by hand using a T-handle socket drive. Took some time, but it worked great and it didn't snap. All in all, great product.
Review: Perfect for flawless quick taps! - Works great with 1/4 hex impact driver, can use with use a drill press or handheld one with a slip clutch, but as the torque will cause a twist with your hand and break the hardened bit if you aren’t careful

## Questions & Answers

**Q: Will these drill & tap 1/4" thick cast iron?**
A: Thanks for your question. 
The max depth of drilling and tapping for this product is 4mm. 1/4" equals to 6.35mm. So it's too thick. 
This kind of combination drill & tap bits are only suitable for thin metal sheets, no matter what the brand is.
In addition, it's suggested that you use M2 HSS bits or M35 cobalt bits to drill cast iron.

**Q: What’s the three count example 1/4 what 20 - 28 kinda important**
A: Thanks for your question. 
Take BSW 1/4-20 as an example. "BSW" means British Standard Whitworth screw thread series. "1/4" is the inch diameter of the bit. "20" means 20 threads per inch.
Try to search the keyword "BSW size" on Google or Bing and you'll learn more.

### ⭐⭐⭐⭐ Be aware
*by A***R on January 11, 2019*

I should have read more the product more closely. I would not recommend using these combo drill/taps in steel thicker than 2/4" steel, and use a drill driver with an adjustable clutch on a low setting. I tried drilling/tapping 1/2" steel bar, and broke one when tapping, and one when trying to back out of the tapped & chamfered hole.
