Osg 653043812 Taper Length Drill Bit 7/16 in Carbide

Product Description

The OSG 653043812 is a solid carbide taper length drill bit designed for precision hole-making in demanding machining applications. Built to Series 6530 specifications, it features a 140-degree split point, a spiral flute geometry, and a straight shank measuring 7/16 inch in diameter. The EgiAs coating provides surface protection suited for high-speed cutting conditions. At 0.4375 inches in diameter with a flute length-to-diameter ratio of 10xD, this bit delivers extended reach without sacrificing rigidity. X-thinned web geometry reduces entry force and improves chip evacuation. Coolant-through capability supports sustained cutting in deep-hole operations where heat management is critical.

This drill bit is suited for metalworking and machining environments where taper length reach is required beyond standard jobber-length drill bits. Typical applications include through-hole drilling in ferrous and non-ferrous metals, mold and die work, aerospace component machining, and production environments running CNC machining centers or drill presses with coolant delivery. The straight shank fits standard drill chucks and collet systems sized for 7/16 inch tooling. It is installed by machinists and CNC operators in job shops, tool rooms, and production facilities.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle for reduced thrust and self-centering entry
• 10xD flute-to-diameter ratio provides extended reach for deep-hole work
• X-thinned web reduces cutting resistance and improves chip flow
• EgiAs surface finish coating for enhanced tool life in demanding cuts
• Coolant-through design supports high-speed deep drilling with internal coolant delivery
• Right-hand spiral flute for standard cutting direction in CNC and manual setups

Compatibility

Designed as an OEM-style replacement taper length drill bit for use in standard drill chucks and collet systems accepting a 7/16 inch straight shank, including CNC machining centers, drill presses, and similar machine tool setups.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit. Verify the shank is seated fully and the chuck or collet is torqued to the machine manufacturer's specification. Confirm coolant-through lines are connected and flow-tested before initiating deep-hole cycles to prevent heat buildup and premature tool wear.
