Sgs 51045 Solid Carbide Jobber Drill Bit No. 45 Wire

Product Description

The SGS 51045 is a solid carbide jobber length drill bit sized to wire gauge No. 45, with a decimal diameter of 0.082 inches and an overall length of 1.75 inches. The bit features a 118-degree faceted point angle with web thinning for easier entry and reduced thrust. The bright uncoated finish and micrograin carbide substrate make it well suited for drilling hard, abrasive, or work-hardening materials where high-speed steel bits lose edge life prematurely. Two spiral flutes in a regular helix evacuate chips efficiently, and the straight-cylindrical shank seats securely in standard drill chucks without slipping. This bit conforms to DIN 338 standards.

The SGS 51045 is used in precision drilling applications across metal fabrication, HVAC panel work, electrical enclosure fabrication, and light industrial maintenance where small-diameter accuracy is required. The 0.082-inch diameter is a common size for tapping 2-56, 3-48, and similar fine-thread patterns. It is appropriate for use in CNC drilling stations, drill presses, and handheld pneumatic or electric drills when positional control is maintained. The 5xD flute-to-diameter ratio provides sufficient flute length at 0.875 inches to handle typical through-hole and blind-hole depths in thin to medium stock.

Key Features

• Solid micrograin carbide construction for extended edge life in hard and abrasive materials
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Bright uncoated finish compatible with a wide range of cutting fluids and materials
• DIN 338 standard compliance ensures consistent dimensional tolerances
• Diameter tolerance of -0.0005 to 0.0000 inches holds close-fit hole requirements
• Tapered web configuration adds rigidity without increasing chip packing risk

Compatibility

Designed as an OEM-style replacement or direct substitute for No. 45 wire gauge jobber length drill bits in standard straight-shank drill chucks conforming to DIN 338 specifications.

Installation Notes

This bit is installed by a machinist, tool-and-die technician, or trade professional using a drill press, CNC spindle, or handheld power drill with a compatible chuck. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Always use appropriate cutting fluid or coolant for the workpiece material, and reduce feed pressure as the bit exits the far side of the material to avoid chipping the carbide tip. Carbide is brittle - avoid lateral loading or impact.
