T34127 60-Piece M35 HSS Cobalt Numbered 1–60 Drill Bit Set

Premier quality numbered drill bits from the Grizzly PRO line.

Experience exceptional performance with this M35 HSS cobalt numbered drill bit set. No need for frequent replacements with these durable drill bits on-hand!

Numbered bits range in size from 60 (smallest) to 1 (largest). Although not included here, numbered bits (T34126) are immediately followed in size by lettered bits from A–Z.

These bits are made of M35 HSS alloy, containing 5% cobalt, allowing increased hardness compared to regular HSS (high-speed steel) drill bits. This hardness helps maintain the cutting-edge sharpness and extends the lifespan of the drill bits.

Additionally, the 5% cobalt enhances the drill bits' heat resistance, allowing them to withstand higher temperatures during drilling. This is particularly beneficial when drilling into tough and hard materials.

The fully ground flutes of these drill bits provide improved cutting results, greater chip evacuation, and minimized heat production to avoid workpiece damage.

This numbered drill bit set comes in a durable metal case for convenient storage and protection.
