Accupro 89699003 Solid Carbide Spotting Drill 4mm

Product Description

The ACCUPRO 89699003 is a solid carbide spotting drill designed to create precise, accurate starting points for follow-on drilling operations. Built with a 120-degree drill point angle, it reduces walking and ensures center accuracy on flat, angled, and curved workpiece surfaces. The cutting diameter measures 4mm (0.1575 inches) with a matching 4mm straight-cylindrical shank. Overall length is 51mm (approximately 2.008 inches), and the spiral flute length is 14mm (0.551 inches). The bright, uncoated finish suits general-purpose spotting across a wide range of workpiece materials. This tool is installed by machinists and toolroom technicians in CNC and manual drill press setups.

The 89699003 is suited for general-purpose spotting applications in production machining, job shop, and toolroom environments. Its single-ended, right-hand cut design fits standard drill chucks and collet holders accepting a 4mm straight-cylindrical shank. The two-flute spiral geometry promotes chip clearance during the shallow spotting operation. It is appropriate for use on machining centers, CNC lathes with live tooling, and manual drill presses where center location accuracy is required before full drilling depth is achieved.

Key Features

• 120-degree drill point angle for accurate center spotting and reduced drill walking
• Solid carbide construction for rigidity and wear resistance in general-purpose applications
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy at small diameters
• Two-flute spiral geometry promotes chip evacuation during spotting cycles
• Right-hand cut, single-ended design compatible with standard collet and chuck toolholding
• 4mm straight-cylindrical shank fits common drill chucks and ER collet systems

Compatibility

Designed as a general-purpose spotting drill for use in any toolholder accepting a 4mm straight-cylindrical shank, including ER collet chucks and standard keyless drill chucks on CNC and manual machine tools.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the 4mm shank fully within the collet or chuck to the recommended grip depth before tightening. Confirm spindle speed and feed rate are appropriate for solid carbide tooling in the workpiece material before running the cycle. Spotting depth should be set to produce a chamfer diameter slightly larger than the follow-on drill diameter — do not use this tool as a full-depth drill.
