The parts can be assembled or disassembled without great force using a rubber mallet. Demountable fits. to" is adequate for installation of press fit bushings or liners. Chip Clearance: To maximize hole accuracy and minimize drill bending, mount drill bushings as close to the workpiece as possible while still allowing adequate chip clearance.

The necessary clearance depends on workpiece material and chip stringiness. Slip-Fixed Renewable Bushings of different lengths provide for both accuracy and chip removal during multiple operations. For example, a short bushing during drilling will provide the proper clearance for chips to escape.

Optional materials such as tungsten carbide Grade C2 carbide with steel head, steel, A2 tool steel, D2 tool steel, M2 tool steel, stainless, C stainless, PH stainless, stainless, bronze, Ampco 18 bronze, Ampco 21 bronze, Oilite, and brass are available as specials.
