YOKOCUT 1/16 Inch Cobalt Set

The YOKOCUT 10PCS drill bit set uses HSS M35 cobalt steel with an AlTiN coating for stainless steel and hardened metal drilling. It suits professional tradespeople and serious DIY users who need reliable performance in tough materials. The 135-degree split point allows penetration without a pilot hole. The round shank locks securely into standard drill chucks for portable use.

Check Chuck Capacity and Material

Verify that your drill chuck accepts a 1/16 inch round shank before ordering. Confirm the workpiece material matches the listed compatibilities such as stainless steel, hardened steel, aluminum, copper, brass, hardwoods, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, and composites. The bits are not intended for masonry, glass, or ceramic tile. Ensure your drill provides adequate torque for metalwork.

M35 Steel and AlTiN Coating

The M35 high-speed steel construction with Titanium Aluminum Nitride coating delivers hardness and heat resistance for extended tool life. The dual coating improves lubrication during cutting and adds corrosion protection. The 135-degree point angle reduces walking and clogging in high-tensile materials. Round shanks provide consistent grip in three-jaw chucks without slippage during heavy feed pressure.
