Accupro 89699029 Carbide Spotting Drill 90 Deg 5mm

Product Description

The ACCUPRO 89699029 is a solid carbide spotting drill designed to create precise starter holes for follow-on drilling operations. Ground to a 90-degree point angle, it accurately centers twist drills and reduces walking on entry. The 5mm cutting diameter and 5mm straight-cylindrical shank keep the setup simple and compatible with standard collet and chuck systems. At 51mm overall length with a 20mm spiral flute, this drill is suited for general-purpose spotting in ferrous and non-ferrous materials. The bright uncoated finish makes it a cost-effective option where specialized coatings are not required.

This spotting drill is used in precision machining environments including job shops, production lines, and tool rooms. It is appropriate for CNC machining centers and manual mills where accurate hole location is critical before drilling, countersinking, or tapping. The right-hand cutting direction and two-flute spiral design clear chips efficiently during shallow spotting passes. General-purpose performance suits a wide range of materials including mild steel, aluminum, and plastics at standard cutting parameters.

Key Features

• 90-degree point angle for accurate drill centering and reduced entry deflection
• Solid carbide construction for rigidity and longer tool life compared to high-speed steel
• 5mm cutting diameter with matching 5mm straight-cylindrical shank
• Two-flute spiral design promotes chip evacuation during spotting passes
• Bright uncoated finish suitable for general-purpose applications
• Single-ended, right-hand cut configuration

Compatibility

Designed as a general-purpose spotting drill compatible with standard 5mm collets, ER collet chucks, and drill chucks used on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully stopped and the control in a safe state. Secure the straight shank in a properly sized collet or chuck and verify runout before beginning cuts. Spotting drills are intended for shallow entry operations only and should not be used as full-depth twist drills. Follow the tooling manufacturer and machine builder guidelines for appropriate spindle speeds and feed rates for the workpiece material.
