Titan Usa SD91441 Reduced Shank Drill Bit 41/64 in Hss

Product Description

The TITAN USA SD91441 is a reduced shank twist drill bit machined from high-speed steel (HSS) and designed for drilling precise holes in metal, wood, and plastic. The bit features a 41/64-inch cutting diameter (0.6406 inches decimal) paired with a 1/2-inch reduced shank, allowing it to chuck into standard 1/2-inch drill chucks and presses without requiring a larger capacity machine. The 118-degree split-point angle is suited for general-purpose drilling across a wide range of materials. A bright, uncoated finish keeps the tool lightweight and easy to inspect for wear. This bit is part of the Series 625 line and is sold individually.

This drill bit is intended for use in machine shops, fabrication facilities, and maintenance environments where a 41/64-inch hole diameter is required but only a 1/2-inch chuck is available. It is well suited to drill press and hand-drill applications in light manufacturing, HVAC equipment fabrication, electrical panel work, and general mechanical assembly. Licensed tradespeople and skilled maintenance technicians are the primary installers and users of this tool.

Key Features

• Reduced 1/2-inch shank allows use in standard 1/2-inch drill chucks despite the larger 41/64-inch cutting diameter
• High-speed steel construction provides heat resistance and durability across metal, wood, and plastic substrates
• 118-degree point angle delivers consistent entry geometry for general-purpose drilling
• 3-inch flute length promotes efficient chip evacuation during through-hole drilling
• 6-inch overall length provides reach for deeper workpieces while maintaining rigidity
• Bright, uncoated finish allows easy visual inspection of cutting edge condition

Compatibility

Designed as a general-purpose replacement or stock drill bit compatible with any drill press or hand drill fitted with a 1/2-inch chuck capacity. No specific OEM model compatibility is stated in available product data.

Installation Notes

This drill bit is installed and operated by machinists, fabricators, and trade professionals familiar with rotary cutting tools. Always secure the workpiece firmly before drilling and set drill press speed appropriate to the material and bit diameter. Inspect the cutting edges before each use and replace if chipping or dulling is observed. Never force a dull bit — excessive feed pressure increases heat buildup and can cause premature tool failure or workpiece damage.
