43-Piece Porting and Polishing Kit

The Standard Abrasives DPK-100 is a 43-piece porting and polishing kit designed for professional-grade metal finishing and cylinder head work. It provides a versatile selection of abrasives to help achieve smooth surfaces and refined intake or exhaust ports. The set includes two flapwheels, four CrossBuffs, and a wide array of cartridge rolls, featuring 7 full-tapered, 7 half-tapered, and 21 straight rolls in assorted sizes. Also included are two mounted points and three specialized mandrels—two for cartridge rolls and one for CrossBuffs with set screws—all organized in a durable plastic storage case. This kit is intended for users who require a complete abrasive solution for material removal and surface preparation. Because these components are designed for industrial applications, users should be aware that the materials involved may contain elements noted under Proposition 65 regulations regarding potential exposure to chemicals.
