Sgs 07335 Circuit Board Drill Bit Size 54 Solid Carbide

Product Description

The SGS 07335 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board (PCB) fabrication and similar small-diameter drilling applications. The bit measures 0.0550 inches (wire size 54) in cutting diameter with a 1/8-inch shank diameter and an overall length of 1.5 inches. The 130-degree four-facet point geometry reduces walking and delivers clean entry holes in thin, layered materials. Uncoated solid carbide construction provides the rigidity and edge retention required when drilling through abrasive or composite substrates at high spindle speeds. Licensed machinists, PCB fabricators, and precision machine operators are the primary installers of this tool.

This drill bit is suited for use in CNC drilling machines, drill presses, and precision hand-held equipment where tight positional tolerances are required. The regular spiral with a 30-degree helix angle promotes consistent chip evacuation during through-hole drilling. It is applicable across a wide range of workpiece materials including aluminum, stainless steel, titanium, cobalt alloy, copper alloy, cast iron, nickel, plastics, and fiber-reinforced polymers. The two-flute configuration and tapered web design support clean hole geometry in both metallic and non-metallic substrates common in electronics manufacturing and precision fabrication environments.

Key Features

• Wire size 54 cutting diameter of 0.0550 inches (1.40 mm) for precise small-hole drilling
• 130-degree four-facet point reduces drill walking and improves hole entry accuracy
• Solid carbide construction provides high rigidity and edge retention in abrasive materials
• Regular spiral with 30-degree helix angle supports efficient chip evacuation
• Tapered web configuration reduces thrust force during drilling
• Diameter tolerance held to -0.0003 to +0.0000 inches for tight positional control

Compatibility

Designed for use in CNC PCB drilling machines and precision drill presses accepting a 1/8-inch straight shank. Suitable for drilling aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium workpieces.

Installation Notes

This tool is installed by machinists or PCB drilling technicians in compatible drilling equipment. Ensure the machine spindle and collet or chuck are fully de-energized and at rest before changing bits. Verify the 1/8-inch shank seats fully and is secured without runout before beginning a drilling cycle. Follow machine manufacturer guidelines for spindle speed and feed rate when working with small-diameter carbide tooling, as carbide is brittle and susceptible to breakage under side load or excessive feed pressure.
