Hertel 30210150 Circuit Board Drill Bit No 38 Solid Carbide

Product Description

The HERTEL 30210150 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and high-accuracy machining applications. It carries a No. 38 wire gauge size, equal to 0.1015 inches (2.58 mm) in diameter, with a 130-degree drill point angle suited for clean entry and minimal breakout. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation in tight bore conditions. The bright polished finish reduces friction and aids in maintaining dimensional accuracy across the cut. This bit is sized and configured for use by machinists, PCB fabricators, and precision tooling technicians.

This drill bit is intended for drilling operations where tight tolerances and clean hole geometry are required. It performs in materials including alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium. The 1/8-inch straight shank fits standard drill chucks and collet holders used in CNC drilling equipment, drill presses, and precision hand-held units. The tapered web configuration adds rigidity through the cutting zone, making it appropriate for demanding production environments where hole quality and bit life matter.

Key Features

• No. 38 wire size (0.1015 inches / 2.58 mm) for precision bore diameter
• Solid carbide construction for hardness and wear resistance in tough materials
• 130-degree drill point angle minimizes material deformation at entry
• Fast spiral with 35-degree helix angle for effective chip removal
• Bright polished finish reduces cutting friction and heat buildup
• Tapered web design adds rigidity and cutting stability
• Right-hand cutting direction for standard drill chuck and CNC spindle use

Compatibility

Designed as an OEM-style replacement or standard tooling addition for CNC drilling machines, drill presses, and precision fixtures accepting a 1/8-inch straight shank drill bit.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with high-speed precision drilling equipment. Secure the shank fully in the collet or chuck before operation and verify runout before beginning a drilling cycle. Power down and de-energize the machine spindle before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material being drilled.
