Sgs 51048 Jobber Length Drill Bit Wire 48 Carbide

Product Description

The SGS 51048 is a solid carbide jobber length drill bit sized to wire gauge 48, equivalent to 0.076 inches (1.93 mm) in diameter. Built from micrograin solid carbide with a bright uncoated finish, it delivers precise hole geometry at a 118-degree faceted point angle with web thinning for reduced thrust at entry. The 2-flute spiral design with a regular spiral type promotes chip evacuation in demanding materials. Overall length is 1.75 inches, and the straight-cylindrical shank diameter matches the drill diameter at 0.0760 inches. Diameter tolerance is held to -0.0005 to 0.0000 inches for tight, repeatable fits. Licensed machinists, tool and die makers, and precision fabricators are the primary installers of this bit.

The SGS 51048 is engineered for drilling composite workpiece materials where carbide hardness and edge retention outperform high-speed steel. The 7/8-inch flute length supports a maximum drilling depth of 0.7031 inches, making it well suited for through-holes and short blind bores in thin composite panels and laminated assemblies. With a 5xD flute-to-diameter ratio and tapered web configuration, it maintains stability in CNC machining centers and manual drill presses alike. Series 101 production standards and DIN 338 compliance make this bit a drop-in choice for shops specifying metric-compatible tooling in small-diameter ranges from 0.0500 to 0.1000 inches.

Key Features

• Micrograin solid carbide construction for extended tool life in abrasive composite materials
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Bright uncoated finish maintains sharp edge geometry without coating buildup at small diameters
• DIN 338 compliant straight-cylindrical shank for universal chuck compatibility
• Diameter tolerance of -0.0005 to 0.0000 inches supports precision hole sizing
• 2-flute regular spiral design promotes chip clearance in shallow-to-moderate depth bores

Compatibility

Designed as a DIN 338 Series 101 jobber length drill bit for use in CNC machining centers, manual drill presses, and hand drills with collet or Jacobs-style chucks accommodating a 0.0760-inch straight-cylindrical shank. Primary workpiece material designation is composite.

Installation Notes

Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the diameter class. Solid carbide bits are brittle relative to high-speed steel and should not be used in setups with excessive spindle runout or lateral loading. No coolant-through capability is present on this bit; external coolant or dry cutting is required per shop practice. Follow applicable machine shop safety standards and manufacturer feed-and-speed recommendations for carbide tooling in composite materials.
