Cleveland C24286 Taper Pin Reamer Size 10 Hss

Product Description

The CLEVELAND C24286 is a size 10 taper pin reamer ground from high-speed steel for hole enlarging, hole finishing, and hole shaping operations. It produces a precisely tapered bore to accept standard number 10 taper pins, with a small end diameter of 0.5799 inches and a large end diameter of 0.7216 inches at a 1:48 taper rate. The six-flute spiral geometry with a right-hand cut delivers clean, accurate material removal. A bright, uncoated finish keeps the tool at full ground diameter and suits a wide range of workpiece materials. Machinists and toolroom technicians install this reamer in manual or CNC machine tools where a precise taper pin seat is required.

This reamer is suited for general-purpose production and toolroom work on cast iron, steel, and steel alloy workpieces. It is commonly used when assembling or repairing mechanical joints that rely on taper pins for positive alignment and load transfer, such as machine spindles, shafts, and fixture components. The 5/8-inch square shank provides solid drive engagement in standard reamer holders and tap-and-die sets on manual mills, lathes, and drill presses.

Compatibility

Designed to produce standard number 10 taper pin holes in cast iron, steel, and steel alloy workpieces where a 1:48 taper rate is specified.

Installation Notes

This reamer should be installed by a qualified machinist familiar with cutting tool setup and speeds-and-feeds selection. Secure the square shank firmly in the appropriate holder before operation and ensure the workpiece is rigidly clamped to prevent movement during reaming. Apply cutting fluid appropriate for the workpiece material to prolong tool life and improve finish quality. Never force the reamer through undersized stock in a single pass; step up progressively from a drilled pilot hole to avoid tool breakage.
