Titan Usa SD93645 Cobalt Drill Bit 45/64 in 135 Deg

Product Description

The TITAN USA SD93645 is a reduced shank cobalt drill bit designed for drilling through hard and abrasive materials where standard high-speed steel bits fall short. Built to Series 622 specifications, it features a 45/64 inch cutting diameter paired with a 1/2 inch reduced shank, allowing it to seat in standard 1/2 inch chucks without requiring a larger chuck capacity. The 135-degree split point angle reduces walking on entry and requires less feed pressure than conventional 118-degree points. The bright, uncoated finish is standard for cobalt alloy construction. Overall length is 6 inches with a 3 inch flute length and 2 flutes for efficient chip evacuation.

This bit is suited for metalworking applications in industrial, commercial, and shop environments. Machinists, maintenance technicians, and fabricators use this size when drilling through stainless steel, hardened steel, cast iron, titanium, and other tough alloys. The reduced shank design makes it practical on drill presses, milling machines, or hand-held power drills equipped with a standard 1/2 inch chuck where a full-size shank of this cutting diameter would otherwise require a larger collet or chuck upgrade.

Key Features

• 45/64 inch cutting diameter with 1/2 inch reduced shank for use in standard 1/2 inch chucks
• 135-degree split point reduces bit walking and lowers required feed pressure on hard materials
• Cobalt alloy construction provides heat resistance and extended tool life on tough metals
• 3 inch flute length with 2 flutes promotes chip clearance during deep drilling
• 6 inch overall length accommodates a range of workpiece thicknesses
• Bright, uncoated finish — no coating to crack or peel under high heat

Compatibility

Designed as an OEM-style metalworking drill bit compatible with any drill press, milling machine, or power drill equipped with a standard 1/2 inch chuck or larger.

Installation Notes

Installation of this bit should be performed by a qualified machinist or maintenance technician familiar with rotary cutting tools. Secure the reduced shank fully in the chuck and verify there is no runout before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before drilling. Disconnect power to any machine before changing bits.
