Sgs 56106 Straight-flute Carbide Drill Bit 3/32 Inch

Product Description

The SGS 56106 is a straight-flute carbide drill bit designed for precision drilling in hard and abrasive materials. Built from micrograin carbide with a bright uncoated finish, this bit features a 140-degree standard point angle and a web-thinned geometry that reduces thrust and improves centering on entry. The 3/32 inch diameter (0.0938 inches decimal) pairs with a 3/4 inch flute length and a 1-3/4 inch overall length, making it well suited for short, controlled holes in tight workspaces. Right-hand cutting direction, two flutes, and DIN 6539 construction standards round out a tool built for reliable performance in demanding materials.

This drill bit is intended for use on cast iron, hardened steel, and other hardened materials where standard high-speed steel tooling underperforms or fails prematurely. The straight-flute design is preferred over spiral flutes when chip evacuation is less critical and rigidity is the priority, such as when drilling brittle or hard materials. Typical applications include maintenance and repair work, precision metalworking, and toolroom operations where tight diameter tolerances are required. The 3xD flute-to-diameter ratio and 0.609 inch maximum drilling depth make this bit suitable for shallow, accurate holes rather than deep-bore work.

Key Features

• Micrograin carbide construction for extended tool life in hardened and abrasive materials
• 140-degree standard point angle with web-thinned geometry for improved entry and reduced thrust
• Straight-flute design provides added rigidity when drilling cast iron and hardened steel
• Bright uncoated finish maintains sharp cutting edge without coating buildup concerns
• Diameter tolerance of +0.0000 to -0.0005 inches for consistent, precise hole sizing
• Meets DIN 6539 construction standard

Compatibility

Designed for use on cast iron, hardened steel, and hardened materials in applications requiring a 3/32 inch straight-flute carbide drill bit conforming to DIN 6539 Series 106 specifications.

Installation Notes

This tool is installed by machinists and maintenance technicians using a drill press, CNC machine, or hand drill with an appropriate collet or chuck rated for the 0.0938 inch shank diameter. Secure the workpiece firmly before drilling and verify spindle speed matches the recommended surface footage for carbide tooling in the target material. Coolant-through is not supported on this bit; use external coolant or cutting fluid appropriate for the workpiece material if needed. Inspect the cutting edges before each use and remove the bit from service if chipping or wear is visible.
