Osg 652043811 Taper Length Drill Bit 7/16 in Solid Carbide

Product Description

The OSG 652043811 is a solid carbide taper length drill bit designed for precision hole-making in demanding machining applications. Ground to a 140-degree split point with X-thinned web geometry, it starts on contact without a center punch and reduces thrust load through the cut. The EgiAs coating provides a hard, low-friction surface that extends tool life in ferrous and non-ferrous materials. At 7/16 inch (0.4375 inch) diameter with a straight cylindrical shank, this bit fits standard drill chucks and collet toolholders. Coolant-through capability allows cutting fluid delivery directly to the tip, making it well-suited for deep-hole work in CNC machining centers and drill presses.

This taper length drill bit is used in production and precision machining environments where a longer flute reach is required beyond standard jobber length. The 8xD flute-to-diameter ratio and 122 mm flute length give access to deeper bores while the 194 mm overall length keeps the setup rigid. Typical applications include component manufacturing in aerospace, automotive, die and mold, and general metalworking. Installation is performed by machinists and tool-and-die professionals setting up CNC equipment or manual machine tools.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle with X-thinned web for self-centering and reduced thrust
• EgiAs coating extends tool life and improves chip evacuation
• Coolant-through design delivers fluid directly to the cutting edge for deep-hole applications
• Right-hand spiral flute with straight cylindrical shank for standard toolholder compatibility
• 8xD flute-to-diameter ratio provides extended reach for deeper bore requirements

Compatibility

Designed as an OEM-style taper length drill bit for use in CNC machining centers, drill presses, and manual milling machines accepting a 7/16 inch straight cylindrical shank toolholder or collet.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder torque and runout procedures for the machine in use. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a cut. Coolant-through lines should be confirmed clear and at proper pressure before engaging the drill in deep-hole operations.
