Corrosion-Resistant Press-Fit Drill Bushings
 |
These bushings are made of stainless steel for corrosion resistance. Mount flush with jig plates for precise drilling. Drill bushings can also be used as spacers, shims, and machinery bushings.
Also Available: Other sizes. Please select 8504A999 and specify ID, OD, and length.
303 Stainless Steel—303 stainless steel provides excellent corrosion resistance.
440C Stainless Steel—440C stainless steel is harder than 303 to resist wear. It provides good corrosion resistance.
