Hertel 30005950 Circuit Board Drill Bit No 53 1.51mm

Product Description

The HERTEL 30005950 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and light machining applications. Sized to wire gauge No. 53, it measures 1.51mm (0.0595 inches) in both drill diameter and shank diameter, with a 118-degree drill point angle that promotes accurate entry and clean hole geometry. The fast spiral flute design with a 35-degree helix angle clears chips efficiently at high spindle speeds. The tapered web configuration adds rigidity and reduces wandering on entry. This bit is intended for use by machining professionals, electronics fabricators, and precision drilling technicians.

This drill bit is suited for high-speed drilling in cast iron, non-ferrous metals, and steel, as well as PCB substrates where tight dimensional tolerances are required. The bright polished finish reduces friction and helps extend tool life in production environments. With a right-hand cutting direction and fast spiral geometry, it performs well in CNC drilling setups and manual drill presses where consistent hole quality is critical. The compact overall length of 1.5 inches keeps the tool stiff and minimizes deflection in small-diameter applications.

Key Features

• Wire gauge No. 53 sizing at 1.51mm (0.0595 inches) diameter for precision small-hole drilling
• Solid carbide construction for hardness, wear resistance, and dimensional stability
• 118-degree drill point angle for accurate entry and reduced walking
• Fast spiral flute with 35-degree helix angle for efficient chip evacuation at high RPM
• Tapered web configuration adds rigidity and reduces deflection
• Bright polished finish minimizes friction and extends tool life
• Right-hand cutting direction, compatible with standard drill press and CNC spindle rotation

Compatibility

Designed as a replacement or production-use circuit board drill bit for applications requiring wire gauge No. 53 hole sizing in cast iron, non-ferrous metals, and steel.

Installation Notes

Installation and use of this drill bit should be performed by qualified machining or electronics fabrication technicians familiar with small-diameter carbide tooling. Carbide bits are brittle and should never be used in flex-shaft or hand-held rotary tools where lateral forces may cause breakage. Ensure the spindle and collet are clean and properly seated before use, and verify that feed rate and spindle speed are appropriate for the work material and bit diameter. Power down and lock out the machine before changing tooling.
