Description
- 【High Strength Material l】:Made of high speed steel (HSS) with excellent hardness and wear resistance. It not only keeps sharp in high-speed cutting, but also resists thermal deformation and prolongs service life.
- 【All-in-one Drilling and Tapping】:The 3-in-1 combination drill and tap bit set can complete hole drilling, tapping, and countersinking. Three processes in one, one-step operation, greatly saving processing steps, improving work efficiency, and providing accurate processing results. Used to create threaded holes, great for situations where both drilling and tapping are required.
- 【Combination Drill and Tap Bit】:The bit set includes 12 different sizes of tap drills, covering common sizes in metric (M3×0.5 to M10×1.5) and imperial SAE (1/4-20NC to 6-32NC). In addition, it is specially equipped with a 1/4-inch quick-change adapter for quick and easy connection of different tools. Fit Electric hand drill, impact drill, bench drill, electric screwdriver and other tap machines
- 【Easy to Wet and Dry Use】:Whether it is dry drilling or wet cooling operation, this set can easily cope with it. Dry drilling is suitable for fast and convenient processing scenarios; while wet cooling can effectively reduce cutting temperature, reduce tool wear and prolong service life.
- 【Widely Use 】:These drill-tap bits are must have if you fabricate a lot; you can use them in aluminum, plastic, wood and other thin soft material metal panel; When you use it, make sure it is perfectly straight, take your time, go slow, use lubrication to prevent breaking the bit in the hole
