Sgs 51074 Jobber Drill Bit Wire 74 0.0225 in Carbide

Product Description

The SGS 51074 is a solid carbide jobber length drill bit in wire gauge size 74, with a decimal diameter of 0.0225 inches (0.57 mm). It features a 118-degree faceted point angle with web thinning for reduced thrust and cleaner entry. The regular spiral flute geometry and right-hand cutting direction suit high-precision drilling applications in composite materials and other challenging substrates. Built from micrograin carbide stock, this bit delivers the rigidity and edge retention that carbide is specified for when tolerance and repeatability matter. It conforms to DIN 338 standards and carries a bright uncoated finish.

The SGS 51074 is designed for use in precision drilling operations where tight hole tolerances are required. With a diameter tolerance of -0.0005 to 0.0000 inches, it is well suited to applications in composite fabrication, aerospace component work, and other industries where small-diameter, close-tolerance holes are common. The straight cylindrical shank fits standard drill chucks and collet holders used in CNC machining centers, drill presses, and handheld precision tools. It is sold individually and is appropriate for machinists, tool and die technicians, and composite fabricators working at small diameters.

Key Features

• Wire gauge size 74 with 0.0225-inch decimal diameter for small-bore precision work
• 118-degree faceted point with web thinning reduces cutting thrust and improves entry accuracy
• Micrograin solid carbide construction provides hardness and edge retention beyond standard HSS bits
• Right-hand cut with regular spiral flute for efficient chip evacuation in 2-flute configuration
• Bright uncoated finish; DIN 338 compliant straight cylindrical shank
• Diameter tolerance of -0.0005 to 0.0000 inches ensures repeatable hole sizing

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 0.0225-inch straight cylindrical shank. Primary workpiece material designation is composite per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists or fabrication technicians familiar with small-diameter carbide tooling. Secure the straight shank fully in a compatible collet or drill chuck before operation to prevent runout. Carbide bits are brittle compared to HSS - avoid side loading, interrupted cuts without adequate support, or excessive feed rates that risk tip fracture. Follow machine manufacturer guidelines for spindle speed and feed rate when drilling composite or hard materials at this diameter.
