Titan Usa CD68631 Extra Length Drill Bit 31/64 in Hss

Product Description

The TITAN USA CD68631 is an extra length, high speed steel drill bit designed for deep-hole drilling applications where standard-length bits fall short. It features a 31/64 inch diameter, a 118-degree standard point angle, and an uncoated HSS construction that delivers reliable performance across a wide range of ferrous and non-ferrous materials. With a 12-inch overall length and a 9-inch spiral flute, this bit clears chips effectively during extended drilling operations. It is a right-hand cutting, two-flute design with a straight-cylindrical shank sized at 31/64 inch for secure chuck engagement. Machinists, pipefitters, ironworkers, and maintenance trades use this type of bit when penetrating thick stock, structural steel, or deep assemblies.

This extra length drill bit is suited for industrial and trade applications where through-hole drilling in thick materials, deep structural members, or stacked workpieces is required. The Series 686 designation places it in a family of extended-reach HSS bits appropriate for stationary drill press use, magnetic drill setups, and heavy-duty hand drilling. The uncoated finish makes resharpening straightforward, and the spiral flute geometry helps maintain consistent chip evacuation in both metal and wood substrates.

Compatibility

Designed as a direct-use extra length drill bit for any chuck accepting a 31/64 inch straight-cylindrical shank, including standard keyed and keyless drill press chucks and magnetic drill adapters.

Installation Notes

Installation of this bit is performed by machinists, pipefitters, ironworkers, or general maintenance technicians. Secure the straight shank fully into the chuck before operation and verify chuck key is removed before starting the machine. Use appropriate cutting fluid or coolant when drilling hardened or thick steel to extend edge life, and reduce feed pressure near breakthrough to prevent grab or workpiece movement. Wear appropriate eye and hand protection per shop safety standards.
