Sgs 56007 Carbide Straight-flute Drill Bit No. 7

Product Description

The SGS 56007 is a straight-flute carbide drill bit designed for precision drilling in ferrous and hardened materials. Manufactured from micrograin carbide with a bright uncoated finish, this bit features a 140-degree point angle and a web-thinned tip for reduced thrust and improved centering. The bit measures 0.2010 inches in diameter (No. 7 wire size), with a 1.1875-inch flute length and a 2.25-inch overall length. Cutting direction is right-hand, and the two-flute straight configuration makes it well-suited for materials that produce short, brittle chips. It conforms to DIN 6539 standards.

The SGS 56007 is intended for drilling cast iron, steel, and hardened steel in precision machining environments. Straight-flute geometry is preferred over spiral flutes when working with materials prone to chip clogging or when hole geometry requires rigid chip evacuation control. The 3xD flute-to-diameter ratio and 0.9530-inch maximum drilling depth make this bit appropriate for shallow to moderate-depth holes in production or maintenance machining applications. It is sold individually and typically used by machinists, toolroom technicians, and maintenance professionals working with metal fabrication or repair.

Key Features

• Micrograin carbide construction provides hardness and wear resistance for ferrous and hardened workpiece materials
• 140-degree point angle reduces thrust and improves entry accuracy on hard materials
• Web-thinned tip decreases cutting resistance and supports self-centering
• Straight-flute design suited for cast iron, hardened steel, and other short-chipping materials
• Bright uncoated finish compatible with a wide range of cutting fluids and dry cutting applications
• Conforms to DIN 6539 dimensional standards for consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or production-use straight-flute carbide drill bit compatible with standard drill chucks and collet holders accepting a 0.2010-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Secure the bit firmly in a drill chuck or collet rated for the shank diameter before operation. Carbide tooling is brittle and should not be used in setups with excessive runout or lateral load. Always verify machine speed and feed rates are appropriate for the workpiece material before drilling.
