Sgs 51075 Jobber Length Drill Bit Wire 75 Carbide

Product Description

The SGS 51075 is a solid carbide jobber length drill bit in wire gauge size 75, with a decimal diameter of 0.021 inches. It features a 118-degree faceted point angle and a regular spiral flute design with web thinning for improved chip evacuation and point stability. The uncoated bright finish exposes the micrograin carbide substrate, which provides the hardness and edge retention needed for small-diameter precision drilling. This bit is designed for use in production and maintenance drilling operations where tight hole tolerances are required. It is sized for installation by machinists, toolroom technicians, and trade professionals working in light fabrication or composite material applications.

The SGS 51075 is suited for drilling composite materials in applications requiring a 0.021-inch diameter hole. With a flute length of 0.25 inches, an overall length of 0.875 inches, and a straight-cylindrical shank diameter of 0.021 inches, this bit fits standard drill chucks and collet systems used in CNC machines, drill presses, and hand-held precision drills. Its 5xD flute-to-diameter ratio and tapered web configuration support clean entry and exit in thin composite workpieces. The Series 101 designation follows DIN 338 standards for jobber length drill bits.

Key Features

• Wire gauge size 75 with 0.021-inch decimal diameter for precision small-hole drilling
• Solid micrograin carbide construction for superior hardness and edge retention
• 118-degree faceted point with web thinning reduces thrust and improves centering
• Regular right-hand spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard chucks and collet holders
• Conforms to DIN 338 jobber length standards for consistent fitment

Compatibility

Designed as a DIN 338-compliant jobber length drill bit for use in standard drill chucks and collet systems that accept a 0.021-inch straight-cylindrical shank. Primary workpiece material is composite.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with small-diameter carbide tooling. Carbide bits are brittle - avoid side loading, off-axis entry, or use in hand-held drills where bit deflection is difficult to control. Secure the workpiece firmly before drilling and confirm chuck or collet runout is within acceptable limits to prevent premature breakage. Consult machine manufacturer guidelines for appropriate spindle speeds and feed rates for carbide tooling at this diameter.
