Accupro A-6100087R Micro Drill Bit 0.0343 in Solid Carbide

Product Description

The ACCUPRO A-6100087R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a 0.0343-inch diameter and a 120-degree drill point angle, this bit delivers accurate entry and consistent hole geometry in hard and abrasive materials. The bright, uncoated finish keeps the carbide surface exposed for direct contact performance without coating buildup concerns. At 30.00 millimeters overall length with a 7.10-millimeter flute length, it is built for controlled, shallow-depth micro drilling. A straight cylindrical shank at 1.50 millimeters diameter seats securely in compatible collets and chucks. This bit is suited for machinists, toolmakers, and precision fabricators working in CNC or manual spindle setups.

The A-6100087R is used in applications requiring small-diameter, high-precision holes in metals, composites, printed circuit boards, and similar hard substrates. The miniature series designation indicates it is engineered for work where standard-size drill bits cannot achieve the required hole size or positional accuracy. Right-hand cutting direction is standard for conventional spindle rotation. It is appropriate for use in machine shops, electronics manufacturing, aerospace component work, and any precision fabrication environment where micro-scale hole drilling is required.

Key Features

• 0.0343-inch diameter for tight-tolerance micro drilling applications
• Solid carbide construction provides hardness and wear resistance in abrasive materials
• 120-degree drill point angle for standard entry geometry and accurate positioning
• Bright, uncoated finish with no coating buildup at cutting edges
• Straight cylindrical shank at 1.50 millimeters for secure collet or chuck seating
• Spiral flute, regular spiral type for consistent chip evacuation

Compatibility

Designed for use in CNC machining centers, drill presses, and manual spindles accepting a 1.50-millimeter straight cylindrical shank. Suitable for precision drilling in metals, composites, and other hard substrates where miniature-diameter holes are required.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom professional. Ensure the spindle and collet are fully stopped and powered down before inserting or removing the bit. Verify collet size matches the 1.50-millimeter shank diameter to prevent runout or slippage. At this diameter, feed rate and spindle speed must be carefully controlled to avoid bit breakage, consult published feeds-and-speeds data for solid carbide micro drills in the target material.
