Cleveland C12124 Taper Shank Drill Bit 5/16 Inch 1MT Hss

Product Description

The CLEVELAND C12124 is a taper shank drill bit designed for general-purpose drilling in metal, wood, and similar materials. It features a 5/16-inch diameter with a Morse Taper 1 shank, making it compatible with taper shank drill presses, lathes, and milling machines that accept MT1 tooling. The 118-degree standard point geometry suits a wide range of materials and everyday drilling tasks. Manufactured from high-speed steel with an oxide finish, this bit delivers reliable wear resistance for production and maintenance environments. A right-hand spiral flute with web thinning reduces thrust and improves chip evacuation during operation.

This bit is suited for machine shops, maintenance facilities, and production floors where taper shank tooling is standard. The MT1 shank seats directly into compatible spindles without a separate chuck, providing rigid, accurate tool holding. With a 3.125-inch flute length and 6.375-inch overall length, it accommodates moderate drilling depths in ferrous and non-ferrous materials. General-purpose classification means it handles a broad range of everyday drilling applications without requiring specialized setup.

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a Morse Taper 1 spindle or sleeve. Suitable for general-purpose drilling in ferrous metals, non-ferrous metals, and similar materials.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with taper shank tooling. Clean the MT1 taper and spindle socket thoroughly before seating to ensure full contact and accurate alignment. Power down and lock out the machine before inserting or removing the bit. Do not use a chuck key or adapter not rated for the MT1 taper, as improper fitment can cause runout or ejection during operation.
