Accupro A-6100165R Micro Drill Bit 1.65 Mm Solid Carbide

Product Description

The ACCUPRO A-6100165R is a miniature-series solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 1.65 mm (0.0650 inch) diameter and a 120-degree point angle, this bit delivers clean entry and accurate hole placement in hard and abrasive materials. The bright, uncoated finish is suited for dry or minimal-lubricant drilling where coating adhesion is not a factor. The right-hand spiral flute geometry promotes efficient chip evacuation in small-diameter work. A straight-cylindrical shank at 2.00 mm diameter provides secure chuck retention in standard collets and precision chucks.

This drill bit is intended for machining, circuit board drilling, instrument manufacturing, and other applications requiring sub-2 mm hole diameters. It is a standard choice in tool rooms, CNC shops, and precision fabrication environments where consistent entry geometry and tight diameter tolerances are required. The miniature series designation indicates it is engineered for small-diameter, high-precision work rather than general-purpose drilling. Each unit is sold individually, with a minimum order quantity of 10 pieces.

Key Features

• 1.65 mm (0.0650 inch) drill diameter for sub-2 mm precision boring
• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree standard point angle for accurate self-centering entry
• Right-hand spiral flute promotes chip evacuation in deep micro holes
• Straight-cylindrical 2.00 mm shank fits standard precision collets and chucks
• Bright/uncoated finish — no coating delamination risk in dry or light-lubrication use

Compatibility

Designed for use in precision collet chucks and standard drill chucks accepting a 2.00 mm straight-cylindrical shank, typical of CNC machining centers, benchtop drill presses, and hand-held precision drilling equipment used in miniature-scale fabrication.

Installation Notes

Installation and use should be performed by machinists or tooling technicians familiar with small-diameter carbide tooling. Carbide is brittle — avoid side-loading, off-axis force, or excessive feed rates that can cause micro-drill fracture. Ensure the spindle and chuck are clean and concentric before seating the shank. Power down and de-energize all machine controls before changing tooling.
