Osg 653021712 Taper Length Drill Bit 7/32 in Carbide

Product Description

The OSG 653021712 is a taper length drill bit engineered for high-performance drilling in demanding applications. Built from solid carbide with an EgiAs coating, it delivers extended tool life and heat resistance in hard or abrasive materials. The 140-degree split point promotes accurate entry and reduces walking on contact. With a 10xD flute-to-diameter ratio and X-thinned web geometry, it handles deep-hole drilling while maintaining chip evacuation efficiency. Coolant-through capability supports high-speed production environments where heat buildup and chip packing are primary concerns. This bit is suited for machinists, toolroom operators, and production drilling setups.

The 653021712 is designed for taper length drilling operations where a longer reach is needed beyond standard jobber-length configurations. Its straight cylindrical shank accepts standard drill chucks and collet holders. The right-hand spiral flute design suits CNC machining centers, drill presses, and manual mills operating on steel, stainless, cast iron, and other hard materials where solid carbide tooling is specified. The EgiAs coating reduces friction and improves surface finish in the cut.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating reduces heat and friction at the cutting edge
• 140-degree point angle for fast, accurate entry with minimal thrust
• X-thinned web reduces cutting resistance and improves penetration
• Coolant-through design supports high-speed and deep-hole drilling
• 10xD flute length ratio enables extended reach applications
• Right-hand spiral flute with straight cylindrical shank for broad toolholder compatibility

Compatibility

Designed as an OEM-style taper length drill bit for use in standard drill chucks and collet systems accepting a 1/4 inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the shank fully in the collet or chuck before operation, and confirm runout is within acceptable limits to prevent premature breakage. Carbide tooling is brittle — avoid side loading or impact conditions. When using coolant-through capability, verify coolant flow before beginning the cut.
