13-piece M35 HSS drill bit set

The set contains thirteen metric twist drills ranging from 1.5 mm to 6.5 mm, covering the sizes most often needed in a machine shop. Each bit is made from M35 high-speed steel and is designed for hard metals such as stainless steel and cast iron. The straight round shank fits standard drill chucks without an adapter.

135° split point and fully ground flutes

A 135° split point prevents the bit from walking at the start of the hole, so no centre punch is required. Fully ground spiral flutes clear chips quickly, reducing friction and heat during normal drilling in steel, aluminium alloy or wood. The geometry keeps cutting temperatures lower and extends bit life in everyday use.

Sustained drilling in hard materials

When used continuously in stainless steel or cast iron, the M35 cobalt alloy retains hardness better than standard HSS, allowing longer cutting intervals before the edge dulls. Coolant or water should be applied to manage heat buildup during extended sessions. The plastic case keeps the thirteen bits organised and protected between jobs.

Questions about this item

How do I install the 135° split-point bits in a drill chuck without them walking?

The 135° split point prevents walking, so no centre punch is needed. Insert the straight round shank fully into the chuck jaws, tighten securely, and keep the bit vertical during drilling.

What maintenance will the M35 HSS bits need after drilling stainless steel or cast iron?

Cool the bits with water or coolant while drilling to extend life. After use, wipe flutes clean, apply light oil to prevent corrosion, and store in the supplied plastic case.

At what diameter does the set's smallest bit become prone to snapping under sustained pressure?

The 1.5 mm bit is the smallest in the 13-piece set. Use it with a pin vise rather than a drill press, and maintain light pressure with coolant to avoid breakage.
