Sgs 07371 Circuit Board Drill Bit 2.4 Mm Solid Carbide

Product Description

The SGS 07371 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related small-hole applications. It measures 2.4 mm (0.0945 inches) in diameter with a 1/8-inch shank (3.18 mm) and an overall length of 1.5 inches (38.10 mm). The 130-degree four-facet point geometry delivers accurate entry and reduced thrust, while the uncoated solid carbide construction maintains edge sharpness through demanding production cycles. The regular spiral flute with a 30-degree helix angle promotes consistent chip evacuation. This bit is suited for technicians and machinists working in electronics manufacturing, precision fabrication shops, and prototype assembly environments.

This drill bit is rated for use on a broad range of workpiece materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. The heavy-duty grade construction makes it appropriate for both low-volume prototype work and higher-throughput production drilling where consistent hole diameter tolerance is required. The short flute length of 0.40 inches (10.16 mm) provides rigidity in small-diameter drilling operations where deflection and runout must be minimized.

Key Features

• Solid carbide construction for wear resistance and dimensional stability across hard and abrasive materials
• 130-degree four-facet point geometry reduces thrust and improves entry accuracy
• 1/8-inch (3.18 mm) shank diameter compatible with standard collet chucks and PCB drilling spindles
• Regular spiral flute with 30-degree helix angle supports chip evacuation in deep or stacked-board drilling
• Uncoated finish maintains consistent cutting geometry without coating buildup risk in fine-tolerance holes
• Tapered web configuration adds core strength while preserving cutting efficiency at small diameters

Compatibility

Designed for use in PCB drilling machines, CNC drill presses, and precision machining centers accepting a 1/8-inch shank. Compatible with workpiece materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium per SGS Series 105 material application ratings.

Installation Notes

Installation and operation should be performed by qualified machinists or electronics fabrication technicians familiar with CNC drilling equipment and small-diameter tooling. Ensure the spindle and collet are clean and free of debris before seating the shank to prevent runout. Verify spindle speed and feed rate settings are appropriate for the workpiece material and bit diameter before starting the cut. Inspect the cutting edges for chipping or wear before each production run, as solid carbide bits can fracture if run in worn or misaligned setups.
