Professional HSS Nitriding Drill Bit Set

The Jonchinjn DBS001 is a 13-piece drill bit set crafted from high-speed steel with a complex nitriding process. It targets furniture assemblers, DIY professionals and general engineering users who need durable bits for metal, wood, aluminum and plastic. The black and gold coated bits offer triple the lifespan of ordinary coated sets.

Quick-Change Hex Shank Compatibility

Each bit features a 1/4 inch hex shank designed for secure engagement with rapid-change chucks on standard power tools and impact drivers. The portable hard plastic case measures 1.1 in x 1.1 in x 4.7 in, allowing effortless size selection and secure transport. The set covers 13 frequently used sizes ranging from 1/16IN to 1/4IN.

118° Split Point Reduces Heat

An optimal 118-degree split point improves concentricity and drilling stability while decreasing friction and heat buildup. Precision fully ground flutes ensure smooth chip movement during operation. Users should monitor heat dissipation and add coolant as needed to counter friction heat, selecting a drill that fits the bit size to avoid breakage.

Questions about this item

Which drill bit size will limit the depth of cut first when drilling through thick material?

The smallest 1/16 inch bit in the 13 piece set restricts penetration depth because its flute length is the shortest.

How much heat builds up during extended drilling sessions with the nitrided HSS bits?

The 118 degree split point reduces friction and heat, but the supplier still advises monitoring heat dissipation and adding coolant as needed during prolonged use.

What chuck type must my drill or driver already have to use these bits?

A 1/4 inch hex quick change chuck is required for the hex shank design to lock securely into standard power tools and impact drivers.
