Sgs 07137 Circuit Board Drill Bit 0.45 Mm Solid Carbide

Product Description

The SGS 07137 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit board fabrication and high-accuracy machining applications. With a 0.45 mm (0.0177 inch) cutting diameter and a 130-degree four-facet point, it delivers clean entry and minimal workpiece delamination. The uncoated solid carbide construction provides rigidity and dimensional stability in demanding materials. Overall length is 1.5 inches with a 0.25-inch flute length and a 1/8-inch (0.1250 inch) shank diameter. The tapered web and 30-degree helix angle support efficient chip evacuation. This bit carries a heavy-duty grade designation and is suited for professional use in machine shop, electronics manufacturing, and precision fabrication environments.

The SGS 07137 is intended for drilling in a wide range of materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. Its small-diameter format and solid carbide body make it a standard choice for circuit board through-holes and micro-feature machining on CNC drill presses and precision drilling stations. Right-hand cut direction suits conventional CNC spindle configurations.

Key Features

• 0.45 mm (0.0177 inch) cutting diameter for precision micro-drilling
• 130-degree four-facet point for accurate centering and clean breakthrough
• Solid carbide construction provides rigidity and long tool life in hard materials
• Uncoated finish suited for non-ferrous metals, plastics, and fiber-reinforced polymers
• 1/8-inch shank diameter compatible with standard CNC collets and drill chucks
• 30-degree helix angle with tapered web for consistent chip evacuation

Compatibility

Designed for use in CNC drilling machines and precision drill presses equipped with a standard 1/8-inch collet or chuck, as typically used in circuit board fabrication and precision machining operations.

Installation Notes

Installation and tool changes should be performed by qualified machinists or electronics manufacturing technicians with the spindle fully stopped and machine power off. Secure the shank in a properly sized collet to the full grip depth before tightening. Use appropriate spindle speeds and feed rates for the workpiece material and bit diameter to prevent fracture of the carbide body. Do not apply lateral force to the bit during operation.
