Kennametal 1015979 DA100 Double Angle Reamer Collet Chuck

Product Description

The KENNAMETAL 1015979 is a DA100 Double Angle Reamer Collet Chuck designed for precision reaming operations in CNC and manual machining environments. It features a 1-inch straight shank and a 2.12-inch projection length, making it suitable for controlled-depth reaming applications where accurate tool positioning is critical. The collet capacity ranges from 1/32 inch to 9/16 inch, accommodating a broad selection of reamer shank sizes. The double angle collet system provides secure tool clamping with a float-from-center tolerance of 0.004 inch, supporting the minor lateral movement required for floating reamer applications. Machinists and tooling technicians install this chuck in machining centers and drill presses.

This collet chuck is used in metalworking shops performing reaming operations on ferrous and non-ferrous workpieces. It is suited for both production and job-shop environments where consistent bore finish and dimensional accuracy are required. The straight shank configuration allows installation in standard tool holders and spindles that accept 1-inch straight shank tooling. Applications include finish reaming of through holes and blind holes in components requiring tight bore tolerances.

Key Features

Compatibility

Designed for use with DA100 series double angle reamer collets. Accepts reamer shanks from 1/32 inch to 9/16 inch in diameter. Compatible with tooling setups that accept a 1-inch straight shank chuck body.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle or tool holder is fully stopped and de-energized before mounting or removing the chuck. Clean the shank and bore mating surfaces before assembly to ensure proper seating and runout performance. Follow the machine tool manufacturer torque and clamping guidelines for straight shank tooling retention.
