Sgs 51130 Jobber Drill Bit 15/32 in 118 Deg Solid Carbide

Product Description

The SGS 51130 is a solid carbide jobber length drill bit with a 15/32 inch (0.4688 inch) diameter and a 118-degree faceted point angle. Built from micrograin solid carbide with a bright uncoated finish, this bit delivers the rigidity and edge retention required for demanding production drilling in metals, composites, and hard materials. The 2-flute, regular spiral design promotes efficient chip evacuation, and the web-thinned tapered web reduces thrust at entry. At 4-3/4 inches overall length with a 3-inch flute length, it fits standard drill chucks and CNC spindles. Machinists, tool-and-die techs, and maintenance professionals are the primary installers.

The SGS 51130 suits drilling applications in ferrous and non-ferrous metals where dimensional accuracy and tool life are priorities. The straight cylindrical shank at 0.4688 inch diameter seats directly in standard drill chucks or collet holders without adapters. It conforms to DIN 338 standards, making it a direct fit in shops that specify metric-equivalent tooling alongside inch-dimensioned setups. Maximum drilling depth is rated at 2.4062 inches, appropriate for through-hole and blind-hole work within the 5xD flute-to-diameter ratio range.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree faceted point with web thinning to reduce entry thrust and improve centering
• Regular spiral, 2-flute geometry promotes reliable chip evacuation
• Bright uncoated finish suitable for use with or without coolant (coolant-through not supported)
• Straight cylindrical shank fits standard drill chucks and collet holders
• DIN 338 compliant for cross-reference with metric tooling catalogs

Compatibility

Designed for use in standard drill chucks, collet holders, and CNC spindles accepting a 0.4688 inch straight shank, conforming to DIN 338 jobber length specifications.

Installation Notes

Installation is performed by machinists and maintenance technicians familiar with rotating cutting tools. Secure the shank fully within the chuck or collet and verify runout before starting. Always power down and lock out the machine spindle before changing or inspecting bits. Do not exceed the maximum drilling depth of 2.4062 inches in a single pass without retracting to clear chips.
