Accupro 89698880 Spotting Drill 1 in Carbide 120 Deg

Product Description

The ACCUPRO 89698880 is a solid carbide spotting drill designed to create accurate center points and chamfers before through-hole or deep-hole drilling operations. It features a 120-degree drill point angle, a 1-inch cutting diameter, and a 4-inch overall length. The two-flute spiral geometry promotes clean chip evacuation and consistent spot geometry on a wide range of workpiece materials. The bright, uncoated finish makes this tool well suited for general-purpose shop environments where coolant or dry cutting is used. Machinists and toolroom professionals install this drill in CNC machining centers, drill presses, and manual mills.

This spotting drill is intended for general-purpose spotting and center-marking applications in production and job-shop environments. Its straight-cylindrical shank fits standard drill chucks and collet holders sized for a 1-inch shank diameter. The 1.75-inch flute length provides adequate depth for spotting operations without excessive tool overhang. Single-ended construction means the full cutting geometry is concentrated at one end, which is typical for precision spotting work where runout control matters.

Key Features

• 120-degree drill point angle for accurate spot placement and chamfering before finish drilling
• Solid carbide construction for rigidity and wear resistance across general-purpose materials
• Two-flute spiral design promotes efficient chip clearance during spotting
• Bright, uncoated finish compatible with dry cutting and standard cutting fluid applications
• Straight-cylindrical shank with 1-inch diameter fits standard collets and drill chucks
• Single-ended, right-hand cut geometry for conventional spindle rotation

Compatibility

Designed for use in CNC machining centers, drill presses, and manual milling machines equipped with toolholders or chucks accepting a 1-inch straight-cylindrical shank. Suited for general-purpose spotting operations on ferrous and non-ferrous workpieces.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or chuck and torque the holder to the toolholder manufacturer's specification. Confirm runout with an indicator before beginning production cuts, as excessive runout will affect spot accuracy and tool life.
