Hertel 30205950 No. 53 Solid Carbide Circuit Board Drill Bit

Product Description

The HERTEL 30205950 is a solid carbide circuit board drill bit ground to a No. 53 wire size with a 0.0595-inch decimal diameter and a 130-degree point angle. The bit features a fast spiral flute geometry with a 35-degree helix angle and a tapered web configuration, which promotes efficient chip evacuation in small-diameter drilling applications. A bright polished finish reduces friction at the cutting edge. The 1/8-inch straight shank and 1.5-inch overall length make this bit compatible with standard precision drill presses and CNC drilling setups used in circuit board fabrication and small-part machining work.

This bit is suited for drilling printed circuit boards and small-diameter through-holes in precision manufacturing and repair environments. The solid carbide construction handles hard and abrasive substrates that would prematurely wear high-speed steel tooling. Material applications listed by the manufacturer include alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium, making this a versatile small-diameter drill for machine shops, electronics fabricators, and maintenance technicians working with tight-tolerance holes.

Key Features

• No. 53 wire size with 0.0595-inch decimal diameter for precise small-hole drilling
• 130-degree point angle optimized for entry accuracy and reduced walking on hard substrates
• Solid carbide construction resists wear on abrasive and hard materials
• Fast spiral flute with 35-degree helix angle promotes chip clearance in deep holes
• Tapered web configuration adds rigidity to the cutting tip
• Bright polished finish reduces friction and built-up edge at cutting surfaces

Compatibility

Designed for use in precision drill presses, CNC drilling machines, and hand-held drill chucks accepting a 1/8-inch straight shank. Listed material applications include alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium.

Installation Notes

This bit is installed and used by machinists, electronics fabricators, and precision maintenance technicians. Secure the 1/8-inch shank firmly in a collet or drill chuck before operation and verify runout is within acceptable limits for the application. Use cutting fluid appropriate for the workpiece material to extend tool life. Inspect the cutting edge before each use, as solid carbide is brittle and susceptible to chipping if dropped or subjected to side loading.
