Kennametal 1015975 DA180 Double Angle Reamer Collet Chuck

Product Description

The KENNAMETAL 1015975 is a DA180 Double Angle Reamer Collet Chuck designed for precision reaming operations on CNC machining centers and manual machines. It features a 3/4 inch straight shank and a 2.88 inch projection length, making it well suited for applications requiring controlled reach and rigid tool support. The collet capacity spans 1/32 inch to 3/4 inch, allowing it to accept a wide range of reamer shank diameters. Through-coolant capability directs cutting fluid directly to the cutting zone, supporting chip evacuation and extended tool life in ferrous and non-ferrous materials. Machinists and tooling setup technicians are the primary users of this chuck.

This collet chuck is used in production and job-shop environments where hole finishing tolerances are tight. The DA180 double angle collet system provides consistent concentricity and repeatability across high-volume reaming cycles. The 0.10 inch float from center accommodates minor misalignment between the spindle and the pre-drilled hole, which is common in floating reamer applications. The 2.38 inch locknut diameter gives technicians a secure grip surface during collet installation and removal. It is appropriate for both vertical and horizontal machining setups.

Key Features

• DA180 double angle collet system for consistent concentricity in reaming applications
• 3/4 inch straight shank for direct spindle or toolholder mounting
• 2.88 inch projection length for controlled reach in confined bores
• Collet capacity range of 1/32 inch to 3/4 inch accommodates varied reamer shank sizes
• Through-coolant design delivers fluid directly to the cutting edge
• 0.10 inch float from center supports floating reamer alignment

Compatibility

Designed for use with DA180 series double angle reamer collets. Consult the collet bore size range of 1/32 inch to 3/4 inch when selecting compatible collets and reamers.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the collet chuck. Use the appropriate collet spanner wrench and locknut wrench sized for the 2.38 inch locknut diameter to avoid damage to seating surfaces. Verify through-coolant port alignment with the machine spindle coolant supply before initiating a cutting cycle.
