Accupro 62760541 Solid Carbide Taper Length Drill Bit

Product Description

The ACCUPRO 62760541 is a solid carbide taper length drill bit designed for high-performance drilling in demanding shop and production environments. Ground to a 140-degree point angle with spiral fluting, this bit delivers clean entry geometry and efficient chip evacuation. The AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life when cutting hardened steels, cast iron, stainless steel, and other difficult-to-machine materials. At 0.5 inches in diameter with a 6.457-inch overall length and a 4.375-inch flute length, this is a taper length format intended for deeper hole applications. Installation and use is handled by machinists and CNC operators in production and job-shop settings.

This drill bit is suited for taper-length drilling operations where standard jobber-length bits lack the reach. The straight shank mounts directly into standard drill chucks, collet chucks, and hydraulic tool holders with 0.5-inch bore capacity. The through-coolant design channels cutting fluid directly to the cutting edge, which is critical when drilling deep holes in ferrous and non-ferrous alloys at elevated feed and speed rates. The 7xD flute-length-to-diameter ratio supports deep-hole entry while maintaining rigidity appropriate for CNC machining centers and drill presses.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 140-degree point angle reduces thrust force and improves self-centering on entry
• AlTiN coating enhances heat resistance for dry or minimal-quantity lubrication cutting
• Through-coolant capability delivers fluid directly to the cutting zone during deep-hole operations
• Spiral flute geometry promotes positive chip flow and reduces recutting
• Taper length format extends reach compared to standard jobber drills at the same diameter

Compatibility

Designed as an OEM-style taper length drill bit for use in CNC machining centers, drill presses, and manual mills equipped with a 0.5-inch straight-shank tool holder or collet system.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the bit from the tool holder. Confirm proper shank engagement depth and tool holder clamping torque per the machine manufacturer's specifications before running the spindle. When using the through-coolant feature, verify that coolant pressure and flow rate are set within the machine tool's operating parameters before beginning the cut.
