Precision Brand 24200 Arbor Spacer Set 19 Piece Steel

Product Description

The PRECISION BRAND 24200 is a 19-piece steel machine tool arbor spacer set designed for precise axial positioning of cutting tools on arbors and spindles. The set covers a thickness range of 0.001 to 0.125 inches, giving machinists and toolroom technicians fine control over cutter spacing and tool-to-workpiece positioning. Each spacer features a 7/8-inch inside diameter, a 1-3/8-inch outside diameter, and a 3/16-inch keyway width to register positively on keyed arbors. The steel construction resists deflection under the lateral and axial loads common in milling and grinding operations. This set is installed by machinists, toolroom operators, and maintenance technicians working with arbor-mounted tooling.

The 24200 spacer set is suited for use with gang cutters, milling cutters, grinding tools, slitting blades, and circular saws mounted on standard keyed arbors. The 0.001-inch minimum thickness allows for very fine stack-up adjustments, making this set useful when precise cutter spacing is critical to part accuracy. Applications include horizontal milling machines, arbor-driven grinders, and slitting setups in production and job-shop environments. The 19-piece assortment provides enough variety to handle a wide range of spacing requirements without custom grinding individual spacers.

Installation Notes

Installation is performed by machinists or toolroom technicians. Always power down and lock out the machine before mounting or removing arbor spacers. Stack spacers in the required combination to achieve the desired cutter position, ensuring the keyway on each spacer aligns with the arbor key before seating the drawbar or arbor nut. Follow the machine tool manufacturer's torque guidance for the arbor nut to prevent spacer distortion or arbor runout.
