Sgs 51069 Jobber Drill Bit Wire Size 69 Solid Carbide

Product Description

The SGS 51069 is a solid carbide jobber-length drill bit in wire gauge size 69, equivalent to 0.0292 inches (0.74 mm) in diameter. Built to DIN 338 standards, it features a 118-degree faceted point with web thinning for reduced thrust and cleaner entry. The micrograin carbide construction delivers the hardness and edge retention needed for demanding drilling applications. At 1.25 inches overall length with a 0.5-inch spiral flute, this bit is suited for precision hole-making where consistent diameter tolerance is critical. Cutting direction is right hand with a regular spiral flute pattern and a straight cylindrical shank.

This drill bit is designed primarily for drilling composite materials, making it a practical choice for aerospace, electronics, and fabrication work where composite laminates and fiber-reinforced panels are common. The bright uncoated finish is appropriate for applications where coating buildup or contamination is a concern. With a flute-to-diameter ratio of 5xD, the bit provides adequate chip clearance for its size class. It is typically used by machinists, tool and die technicians, and precision fabricators working with small-diameter holes in production or maintenance settings.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance in composite drilling
• 118-degree faceted point with web thinning reduces entry thrust and improves hole accuracy
• DIN 338 standard compliance ensures dimensional consistency
• Bright uncoated finish suitable where coating-free tooling is required
• Right-hand cut with regular spiral flute for reliable chip evacuation
• Diameter tolerance of -0.0005 to 0.0000 inches for precision fitment

Compatibility

Designed as an OEM-style jobber drill for use in standard drill chucks and CNC spindles accepting a straight cylindrical shank at 0.0292-inch diameter, consistent with wire gauge tooling in Series 101 applications targeting composite workpiece materials.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Secure the straight cylindrical shank fully in a collet or chuck rated for the shank diameter before operation. Carbide tooling is brittle - avoid side loading, interrupted cuts, or impact that could cause chipping or fracture. Confirm spindle speed and feed rate are appropriate for carbide in composite materials before running the tool.
