Accupro A-6100135R Micro Drill Bit 1.35 Mm Solid Carbide

Product Description

The ACCUPRO A-6100135R is a miniature solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 1.35 mm (0.0531 inches) in diameter with an overall length of 30 mm and a flute length of 11.20 mm. The 120-degree standard point angle promotes accurate entry and reduces walking on hard or dense materials. Solid carbide construction delivers rigidity and wear resistance well beyond high-speed steel, making it a reliable choice for machinists, toolmakers, and precision fabricators working in electronics, medical device, and aerospace component manufacturing.

This bit is suited for micro-drilling operations in materials that demand tight dimensional control and a stable cutting edge. The bright uncoated finish makes it compatible with a wide range of workpiece materials where coating interaction could be a concern. The straight-cylindrical shank at 1.50 mm diameter seats cleanly in standard collet chucks and micro-drill chucks used on CNC machining centers, drill presses, and precision bench-top machines. Right-hand spiral flute geometry clears chips efficiently during through-hole and blind-hole drilling at typical miniature-bit feed and speed parameters.

Key Features

• 1.35 mm drill diameter with 0.0531 inch decimal equivalent for cross-reference
• Solid carbide construction for rigidity and extended tool life
• 120-degree standard point angle for accurate hole entry
• Bright uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut with regular spiral flute for reliable chip evacuation
• 1.50 mm straight-cylindrical shank compatible with standard collet and micro-drill chucks

Compatibility

Designed as an OEM-style miniature drill bit for use in standard collet chucks and micro-drill chucks accepting a 1.50 mm straight-cylindrical shank, as used on CNC machining centers, drill presses, and precision bench-top drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with micro-drill operating parameters. Secure the shank fully in a compatible collet or chuck before operation and verify runout with a dial indicator when tolerance is critical. Do not exceed the tool's rated speed and feed range for the workpiece material. Inspect the cutting edges under magnification before each use, as carbide micro-drills are brittle and susceptible to edge chipping if dropped or mishandled.
