Harvey Tool FBD0787-C3 Flat Bottom Micro Drill Bit 2mm

Product Description

The HARVEY TOOL FBD0787-C3 is a solid carbide flat-bottom micro drill bit engineered for precision drilling where a standard conical point would compromise positional accuracy or hole geometry. Built to a 2.00 mm diameter (0.0787 inches), it features a 180-degree flat point that seats flush at entry without a walking phase, making it well-suited for applications that require a true flat-bottom hole. The AlTiN coating provides thermal and oxidative resistance at elevated cutting temperatures, extending tool life in hard and abrasive materials. With a spiral flute design and right-hand cutting direction, the FBD0787-C3 belongs to the Miniature High Performance Drills - Flat Bottom Drill series.

This drill bit is intended for use in precision machining environments where small-diameter, flat-bottom holes are required. Typical applications include mold and die work, medical device components, electronics fixtures, and aerospace detail parts where hole geometry tolerances are tight. The 4.00 mm shank diameter accommodates standard collet chucks commonly used in CNC machining centers, toolroom mills, and precision drill presses. Machinists and tool-and-die professionals working in ferrous alloys, hardened steels, and non-ferrous materials benefit from the coating and carbide substrate combination this series provides.

Key Features

• 180-degree flat-bottom point produces a flat-floor hole without a conical tip remainder
• Solid carbide construction provides rigidity and wear resistance at small diameters
• AlTiN coating extends tool life in hard and abrasive materials under elevated heat
• Spiral flute geometry promotes chip evacuation in small-diameter bores
• h6 diameter tolerance on the drill ensures consistent fit and repeatable hole sizing
• Right-hand cutting direction compatible with standard CNC and manual spindle rotation

Compatibility

Designed as an OEM-style precision tooling component for use in collet systems and tool holders that accept a 4.00 mm shank diameter, consistent with standard ER and precision collet chuck configurations used in CNC machining centers and toolroom equipment.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or unloading the tool. Seat the shank fully and evenly in the collet to the recommended grip length to prevent runout and tool pullout under cutting loads. Verify spindle speed and feed rate are appropriate for the workpiece material and this diameter before initiating the cut, as micro-diameter carbide tooling is sensitive to runout and axial misalignment.
