Value Collection 526865 Half-round Drill Bit 0.035 in Hss

Product Description

The VALUE COLLECTION 526865 is a half-round drill bit designed for precision deep hole drilling in brass and other soft machining metals. Ground from high-speed steel with a bright uncoated finish, this bit features a straight flute geometry and a 118-degree drill point angle suited to the controlled entry and exit demands of half-round drilling. At 0.035 inches in diameter with a 1.5-inch overall length and a 0.625-inch flute length, it is built for tight-tolerance work in short-run and production environments. The right-hand cutting direction is standard for conventional drill press and CNC spindle operation.

This bit is intended for metalworking applications where a standard twist drill would walk or deflect on curved or pre-drilled surfaces. The half-round profile provides lateral stability against the bore wall, making it appropriate for enlarging or finishing existing holes in brass components, bushings, and similar workpieces. It is commonly used by machinists, tool-and-die technicians, and production drilling operators working with non-ferrous metals in job shop and light manufacturing settings. Each unit is sold individually, with a minimum order quantity of 12 pieces per order.

Key Features

• 0.035-inch drill bit diameter for fine-bore deep hole work
• 118-degree drill point angle for clean entry in non-ferrous metals
• High-speed steel construction provides wear resistance in continuous use
• Straight flute geometry supports chip evacuation in deep hole drilling
• Bright uncoated finish - no coating buildup to affect dimensional tolerance
• Right-hand cutting direction compatible with standard drill press and CNC spindles

Compatibility

Designed for deep hole drilling in brass and soft machining metals; suited for use in standard drill presses, lathes, and CNC machining centers accepting the corresponding shank diameter.

Installation Notes

Half-round drill bits are installed and operated by machinists and tooling technicians familiar with drilling operations in metalworking environments. Secure the workpiece firmly before operation to prevent movement during drilling. Use appropriate cutting fluid for brass to extend tool life and maintain hole quality. Inspect the cutting edge for wear or chipping before each use, as small-diameter HSS bits are susceptible to breakage under side-load or misalignment.
