Migiwata 1.0-10mm Straight Shank Titanium Coated High Speed Steel Twist Drill Bits Set of 19pcs in 19 Sizes for General Purpose

Product Review

OVERVIEW
Made from high-speed steel, these combination drill and tap bits are designed to tap up to 10-gauge wood, plastic and other soft materials. They are not suitable for drill and tap in metals.
These drill taps are a great time saving accessory. Each one is a combination of a twist drill bit and a tap. The point is the same as a twist drill bit, which is self-centering. So, you don't have to buy a centering drill bit or a center punch. Now you can drill and tap at the same time in one operation.
No tool changes, good alignment and fast cycle times make this a very productive tool.
This Migiwata high-speed steel (HSS 4341) drill/tap combination bit set are offered in a set of 6 different metric sizes (M3, M4, M5, M6, M8 and M10).

NOTICE:
It's highly recommended that the combination drill and tap bit is used on a tapping machine.
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.

CAUTION:
Any cutting tool may break or shatter under improper use. Government regulations require use of safety glasses and other appropriate safety equipment at all times in the vicinity of use.

2-IN-1 EFFICIENCY: This combination set is designed to drill the hole and tap the thread in a single operation. By combining two steps into one, it eliminates the need to change bits or use separate tools, significantly speeding up your workflow on repair and fabrication projects.
COMPLETE METRIC RANGE: Includes 6 commonly used metric sizes to suit various needs: M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25, and M10x1.5. Each bit is clearly marked with its size for quick identification and comes in a compact storage case.
1/4" HEX SHANK: Featuring a universal 1/4-inch hex shank, these bits are compatible with most power drills, impact drivers, and quick-change adapters. The hex design provides a secure grip in the chuck, preventing slippage even under torque.
HIGH-SPEED STEEL (HSS): Constructed from industrial-grade High-Speed Steel for durability and wear resistance. The bits feature a spiral flute design that helps clear chips out of the hole efficiently, reducing friction and heat buildup during the tapping process.
VERSATILE APPLICATION: Ideal for drilling and tapping through wood, plastic, and soft metals such as aluminum, brass, and copper. Note: To prevent bit breakage, strictly use low speeds (slow RPM) and apply cutting oil when working with metals. Not recommended for hard metals like stainless steel.
