Sgs 51063 Jobber Drill Bit Wire 63 0.037 in Solid Carbide

Product Description

The SGS 51063 is a jobber-length drill bit designed for precision drilling in composite materials and other demanding substrates. Built from micrograin solid carbide, it delivers the hardness and edge retention needed for clean, accurate holes at small diameters. The bit is sized to wire gauge 63, with a decimal diameter of 0.0370 inches and a 118-degree faceted point angle. The bright, uncoated finish suits applications where coating materials could interfere with tight tolerances. At 1-3/8 inches overall length with a 5/8-inch flute, this bit fits standard jobber-length chucks and collets used across machining and fabrication operations.

This drill bit is intended for use in precision machining environments where small-diameter, tight-tolerance holes are required. It is well suited for drilling composite materials, including fiber-reinforced laminates and similar substrates. The right-hand, regular spiral flute geometry promotes efficient chip evacuation at this diameter range. It is typically used in CNC drilling centers, drill presses, and hand-held pneumatic or electric spindles where runout control is maintained. The straight cylindrical shank allows secure seating in standard collets and chucks. Machinists, toolmakers, and composite fabricators are the primary end users.

Key Features

• Micrograin solid carbide construction for hardness and edge life at small diameters
• 118-degree faceted point angle for accurate hole entry and reduced walking
• Web-thinned, tapered web design reduces thrust force and improves chip flow
• Regular spiral, 2-flute configuration promotes chip evacuation in composite materials
• Bright, uncoated finish maintains close dimensional tolerances
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for use with standard straight-shank collets and chucks accepting a 0.0370-inch shank diameter, conforming to DIN 338 geometry for wire gauge 63 applications.

Installation Notes

This bit should be installed and operated by qualified machinists or toolmakers familiar with small-diameter carbide tooling. Ensure the spindle and chuck are clean and concentric before seating the shank to minimize runout, which is critical at this diameter. Carbide tooling is brittle and will fracture under lateral load or if dropped on a hard surface - handle accordingly. Confirm feed rate and spindle speed are appropriate for carbide tooling at this diameter before beginning a drilling operation.
