Kennametal 1015981 DA200 Double Angle Reamer Collet Chuck

Product Description

The KENNAMETAL 1015981 is a DA200 Double Angle Reamer Collet Chuck designed for precision reaming operations in machine tool applications. This collet chuck features a 1 inch straight shank and a 1-1/2 inch projection, providing the clearance and rigidity required for accurate reaming in tight-tolerance bores. The collet capacity spans 1/64 inch to 3/8 inch, accommodating a broad range of reamer shank diameters. A float-from-center value of 0.0040 inch allows for slight radial compensation, helping the reamer self-align to an existing hole and reducing the risk of bell-mouthing or chatter. Machinists and toolroom technicians use this chuck in CNC machining centers, knee mills, and drill presses where consistent bore finish is required.

This collet chuck is suited for production and job-shop environments performing finish reaming on ferrous and non-ferrous workpieces. The straight shank design allows direct mounting in standard collet chucks or drill chuck holders with matching bore diameter. The DA200 double angle collet system provides a secure, repeatable grip on reamer shanks within the stated capacity range, making it appropriate for both high-volume production runs and precision one-off toolroom work.

Key Features

• DA200 double angle collet system for secure, repeatable reamer holding
• 1 inch straight shank for direct mounting in compatible toolholders
• 1-1/2 inch projection provides clearance for workpiece access
• Collet capacity from 1/64 inch to 3/8 inch covers common reamer shank sizes
• Float-from-center of 0.0040 inch allows radial self-alignment to reduce bore error

Compatibility

Designed for use with DA200 series double angle reamer collets within the 1/64 inch to 3/8 inch collet capacity range. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the collet chuck. Ensure the shank bore and chuck body are clean and free of chips or burrs before seating the shank. Verify collet nut torque and reamer runout with a dial indicator after installation before cutting.
