Titan Usa SD93649 Cobalt Drill Bit 49/64 Inch Reduced Shank

Product Description

The TITAN USA SD93649 is a reduced shank cobalt drill bit designed for drilling through hard metals, stainless steel, and other difficult-to-machine materials. It features a 49/64 inch cutting diameter with a 1/2 inch reduced shank, allowing it to run in standard 1/2 inch chucks while cutting an oversize hole. The 135-degree split point angle reduces walking on entry and lowers the thrust force needed to start the cut. At 6 inches overall length with a 3 inch flute length, it suits both drill press and hand-drill applications. Machinists, maintenance technicians, and industrial tradespeople are the primary installers of this bit.

This drill bit fits applications where a full-shank bit of the same diameter would require a larger chuck. The reduced shank design makes it practical for production drilling, maintenance repair operations, and fabrication shops running standard 1/2 inch capacity drill presses or hand drills. The cobalt steel construction handles elevated cutting temperatures without losing edge hardness, making it well suited for drilling ferrous metals, heat-treated steels, and cast iron. The bright uncoated finish allows visual inspection of the cutting edges between uses.

Key Features

• 49/64 inch (0.7656 inch) cutting diameter with 1/2 inch reduced shank fits standard chucks
• 135-degree split point reduces walking and lowers entry thrust
• Cobalt steel construction resists heat buildup during high-speed drilling of hard metals
• 3 inch flute length provides adequate chip clearance for deep holes
• Bright uncoated finish allows easy edge inspection and regrinding
• Two-flute geometry balances chip evacuation and cutting speed

Compatibility

Designed as an OEM-style replacement or direct-use reduced shank drill bit for any 1/2 inch capacity drill press, magnetic drill, or hand drill requiring a 49/64 inch bore diameter.

Installation Notes

A licensed machinist or qualified maintenance technician should install and operate this bit. Secure the 1/2 inch shank firmly in the chuck and verify the bit runs true before cutting. Always power down the drill press or disconnect the tool from its power source before changing bits or clearing chips. Do not exceed the recommended RPM range for the workpiece material and bit diameter.
