Specification Brand : XJX BulletPoint1 : 【THREE SPIRAL FLUTE STEP DRILL BIT】: Ordinary step drills are easy to deform when cutting. The triple spiral step drill is more stable and smoother when cutting, and prevents metal chips from scattering and improves safety. BulletPoint2 : 【M35 HSS COBALT DRILL BITS】: Cuts a lot more clean holes and much easier than average step drill bits. With 89HRC surface hardness, harder materials can be cut and higher cutting speeds can be achieved. Prefect for Stainless Steel,Metal Sheet,Wood,Plastic,Aluminum Sheet,Copper and other metal sheets. BulletPoint3 : 【NO PILOT HOLES REQUIRED】: The spiral step drill bit drills holes directly into the material without the need for a pilot hole in the flap head. 118°of the divergence point automatically centers the hole, requiring less pressure and preventing slippage. BulletPoint4 : 【34 STEP SIZES】: No need to buy a kit.This 1/4" hex shank step bit set comes with 34 marked sizes so you can drill different hole sizes, saving you time and effort to change bits. Includes three SAE drill bits for steel: 1/8"-1/2" 13 Sizes,1/4"-3/4" 9 Sizes,3/16" - 7/8" 12 Sizes. BulletPoint5 : 【VERSATILE USE】: Our metal drill bit set is perfect for any project such as home repairs, metal working, or any other task that requires precision drilling. Please keep in mind that as the step bit rotates at high speeds, its temperature will continue to increase.

[Tips]: Due to high-speed rotation, the temperature of the drill bit will continue to rise. It is recommended to add cutting oil or spray water to cool down when working continuously, which can effectively improve the service life of the step drill bit.
