T33846 10-Piece M35 Cobalt Quick-Release Hex Shank Step Drill and Drill Bit Set

Unleash high-performance craftsmanship with the ultimate convenience of this comprehensive toolkit.

This set is a versatile and practical solution for DIY projects, woodworking, metalworking, or general repair and maintenance tasks.

All the 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 innovative sharpness and extends the lifespan of the drill bits.

Step drills are designed to incrementally drill through sheet metal and thin stock until reaching the desired hole size.

The two step drills in this set cover hole sizes from 1/8" to 1/2" in 1/16" increments and 3/16" to 7/8" in 1/16" increments.

M35 HSS drill bits with 5% cobalt are well-suited for drilling into hard materials such as stainless steel, cast iron, titanium alloys, and other challenging metals.

The drill bits comes in pairs ranging in size from 1/16" to 1/2".

The quick-release hex shank ensures no slippage when it is used in a drill. The quick release functionality enables use in impact drivers or drills with a quick release chuck.

The set comes in a plastic case for convenient storage and protection.
