Hertel 84578202 Jobber Drill Bit Wire 65 Hss

Product Description

The HERTEL 84578202 is a jobber-length drill bit sized at wire gauge 65 (0.0350 inch decimal equivalent), designed for general-purpose drilling in metal, plastic, and similar materials. Constructed from high speed steel with a bright, uncoated finish, it features a standard 118-degree split point and a right-hand spiral flute for efficient chip evacuation. The straight-cylindrical shank measures 0.0350 inch in diameter, matching the bit diameter for direct chuck mounting. With an overall length of 1.5 inches and a flute length of 0.625 inches, this bit is suited for close-tolerance drilling in tight spaces or thin stock where precision entry is required.

This bit is a standard choice for machinists, maintenance technicians, and fabricators who need reliable small-diameter drilling performance. Wire gauge 65 falls within the 0.0000 to 0.0500 inch size range, making it appropriate for pilot holes, instrument panel work, small fastener clearance holes, and light-duty production drilling. The two-flute spiral design with tapered web and web-thinned point reduces thrust force at entry and helps maintain hole location accuracy on small-diameter work.

Key Features

• Wire gauge 65 size, 0.0350 inch decimal equivalent for precise small-diameter drilling
• 118-degree standard point angle with web-thinned tip reduces entry thrust
• High speed steel construction rated for general-purpose use across common shop materials
• Right-hand cut, regular spiral flute promotes consistent chip clearing
• Straight-cylindrical shank at 0.0350 inch diameter fits standard drill chucks directly
• Bright uncoated finish — no added coating to affect dimensional tolerance on the cutting edge

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks, CNC machining centers, drill presses, and hand drills accepting straight-cylindrical shanks in the 0.0350 inch diameter range.

Installation Notes

Installation and use of small-diameter drill bits should be performed by qualified machinists or maintenance technicians familiar with proper chuck-tightening procedures and appropriate spindle speeds for the material being drilled. Secure the shank fully in the chuck before operation to prevent runout and premature bit breakage. At this diameter, excessive feed pressure is the primary cause of bit failure — use consistent, light feed force. Disconnect power to any equipment before changing bits.
