Hertel 30013600 Circuit Board Drill Bit Size 29 Solid Carbide

Product Description

The HERTEL 30013600 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and light metalworking applications. It features a No. 29 wire gauge diameter of 0.1360 inches (3.45 mm), a 118-degree split-point angle, and a fast spiral flute geometry that promotes efficient chip evacuation at high spindle speeds. The bright polished finish reduces friction and heat buildup during operation. With an overall length of 1.5 inches and a flute length of 0.75 inches, this bit is sized for compact, controlled drilling where positional accuracy is critical. It is typically installed and used by machinists, electronics technicians, and precision fabricators.

This drill bit is suited for drilling cast iron, non-ferrous metals, and steel, making it a versatile choice beyond dedicated PCB work. The tapered web configuration adds rigidity and reduces the risk of bit deflection in tight-tolerance applications. The right-hand cut and 35-degree helix angle are optimized for clean entry and exit holes in thin and medium-thickness materials. It is commonly used in production shop environments, electronics assembly, and prototype fabrication where consistent hole diameter and finish quality are required.

Key Features

• No. 29 wire gauge diameter: 0.1360 inches (3.45 mm) for precise hole sizing
• 118-degree drill point angle suited for cast iron, steel, and non-ferrous metals
• Solid carbide construction for hardness, wear resistance, and dimensional stability
• Fast spiral flute with 35-degree helix angle promotes rapid chip removal
• Bright polished finish reduces friction and heat at the cutting edge
• Tapered web configuration adds core strength and resists deflection

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with standard drill chucks and CNC drilling equipment accepting a 0.1360-inch shank diameter. Suitable for use on cast iron, non-ferrous metals, and steel workpieces.

Installation Notes

This bit should be installed by a qualified machinist or technician in a drill press, CNC drill, or precision hand drill with a compatible chuck size. Ensure the spindle and workpiece are secured before operation. Use appropriate cutting speeds for solid carbide tooling and the specific material being drilled. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed to maintain hole quality.
