Sgs 56054 Straight-flute Drill Bit Wire Size 54 Carbide

Product Description

The SGS 56054 is a straight-flute solid carbide drill bit designed for precision drilling in ferrous and hardened materials. Built to Series 106 standards and conforming to DIN 6539, it features a 140-degree standard point angle with web thinning for improved centering and reduced thrust. The micrograin carbide construction provides the hardness and edge retention needed when drilling cast iron, hardened steel, and general steel. At 0.055 inches in diameter (Wire Size 54) with a 0.5 inch flute length and 1.5 inch overall length, this is a compact, high-precision bit suited for tool and die, maintenance, and production drilling applications.

This drill bit is used in applications requiring tight tolerances and clean entry holes in hard or abrasive workpiece materials. The right-hand cutting direction and uncoated bright finish make it suitable for use with cutting fluids in conventional drilling setups. It is commonly specified by machinists, tool-and-die makers, and maintenance technicians working on steel fabrication, mold work, and precision mechanical assemblies where hole location accuracy is critical.

Key Features

• Solid micrograin carbide construction for use in cast iron, hardened steel, and general steel
• 140-degree standard point angle with web thinning for accurate entry and reduced thrust load
• Straight-flute geometry suited for drilling brittle and hard materials
• Uncoated bright finish compatible with a wide range of cutting fluids
• Diameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing
• Conforms to DIN 6539 standard; Series 106 designation

Compatibility

Designed as an OEM-style replacement or direct-specification straight-flute carbide drill bit for use in standard drill chucks and collet holders accepting a 0.055-inch shank diameter; primary workpiece materials include cast iron, hardened steel, and steel, with secondary compatibility in hardened materials.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with carbide tooling. Ensure the drill press, CNC machine, or hand drill is powered off and secured before mounting the bit in the chuck or collet. Carbide tooling is brittle and susceptible to chipping under lateral load or impact — avoid side forces and do not use this bit for enlarging existing holes by recutting at an angle. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
