[Straightforward Installation]: This double-end straight shank drill bit is widely compatible with various power drills, including bench drills, hand drills, and impact drills. Insert the straight shank into the drill chuck and tighten securely when using. Position the bit perpendicular (90°) to the workpiece; a center punch can be used first to prevent slipping. Adjust the spindle speed and feed rate according to the hardness of the material being drilled.

[Reliable and Durable]: This stubby body drill bit is made of M2 high-speed steel, featuring high hardness and excellent wear resistance, making it suitable for machining medium to high hardness materials. The nitrided black surface finish enhances the bit's surface properties, improving wear and corrosion resistance while extending service life and working efficiency.

Equipped with a 135-degree split point tip, the jobber drill bit delivers outstanding processing stability, is well-suited for harder materials, effectively reduces the risk of cutting-edge chipping, and enhances both drilling efficiency and hole quality.
