Titan Usa CD45527 Mechanics Drill Bit 27/64 in Hss

Product Description

The TITAN USA CD45527 is a mechanics drill bit engineered for precision drilling in metal, wood, and composite materials. Built from high-speed steel (HSS) with a black oxide and gold finish, this bit delivers heat resistance and extended service life under continuous use. The 135-degree split point geometry reduces walking on contact and requires less feed pressure compared to standard 118-degree points. The straight-cylindrical shank measures 27/64 inch in diameter and seats securely in standard drill chucks. At 4-7/16 inches overall length with a 2-7/8 inch spiral flute, it provides efficient chip evacuation and controlled cutting in a compact form factor. Right-hand cut direction is standard for conventional drilling operations.

This bit is suited for use in fabrication shops, maintenance and repair settings, and general mechanical work where accurate hole sizing is required. The 27/64 inch diameter is a common sizing for bolt clearance holes and tap-drill preparation in ferrous and non-ferrous materials. HVAC, plumbing, and electrical trades will find this size useful for sheet metal work, bracket fabrication, and panel knockouts where a precise, clean entry hole is required without a pilot pass.

Key Features

• 27/64 inch diameter with 135-degree split point for self-centering, reduced walking
• High-speed steel construction for heat and wear resistance in metal drilling
• Black oxide and gold finish extends bit life and reduces friction
• Spiral flute design promotes efficient chip removal and prevents clogging
• Straight-cylindrical shank compatible with standard three-jaw drill chucks
• Right-hand cut, Series 455 — sold as a single unit

Compatibility

Designed as a general-purpose mechanics drill bit compatible with any standard drill press, hand drill, or magnetic drill accepting a straight-cylindrical shank in the 27/64 inch diameter range.

Installation Notes

Secure the shank fully into the chuck and confirm the bit is centered before applying power. Use appropriate cutting fluid or lubricant when drilling through hardened or stainless steel to extend bit life and prevent premature dulling. Reduce feed pressure as the bit breaks through the material to avoid grabbing or workpiece movement. Wear appropriate PPE including eye protection when operating any rotary cutting tool.
