Hertel 30019100 Circuit Board Drill Bit No. 11 0.191 in

Product Description

The HERTEL 30019100 is a solid carbide circuit board drill bit designed for high-precision drilling in electronics manufacturing and PCB fabrication environments. Ground to a No. 11 wire gauge diameter of 0.191 inches (4.85 mm), it features a 118-degree drill point angle and a fast spiral flute geometry with a 35-degree helix angle. The tapered web configuration supports chip evacuation and reduces walking at entry. Right-hand cutting direction is standard. This bit is intended for use by machining professionals, PCB fabricators, and precision drilling technicians.

This drill bit is suited for drilling cast iron, non-ferrous metals, and steel. Its fast spiral design makes it effective in circuit board and light-duty precision metalworking applications where tight hole tolerances and clean entry points are required. The bright polished finish reduces friction and helps maintain cutting edge integrity over repeated use cycles. It is sold individually and is appropriate for use in standard drill press, CNC drilling, or manual precision drilling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• No. 11 wire gauge size at 0.191 inches (4.85 mm) diameter
• 118-degree drill point angle with tapered web for accurate entry
• Fast spiral flute with 35-degree helix angle promotes chip clearance
• Bright polished finish minimizes friction during cutting
• Right-hand cutting, compatible with standard drill chucks and CNC spindles

Compatibility

Designed as an OEM-style replacement or standard supply item for circuit board drilling operations requiring a No. 11 wire gauge solid carbide drill bit with fast spiral geometry.

Installation Notes

Installation and use of this drill bit should be performed by qualified machining or electronics manufacturing technicians. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable tolerances for the application. Ensure drilling equipment is powered down and spindle is at rest before inserting or removing the bit. Do not exceed the feed rate or spindle speed recommended for solid carbide tooling in the workpiece material being drilled.
