All American Drill Bushing - 9mm ID X 15mm OD X 20mm L, C1144 Steel, Heat Treated To Rockwell C62-64 (Made In USA)

About This Product

Hey, if you need a solid, reliable drill bushing made right here in the USA, this is the one. It's an All American Type PM Bushing, built tough from domestic C1144 steel. They don't cut corners – it's heat treated all the way to a Rockwell hardness of C62 to C64, which basically means it's super hard and resistant to wear, so it'll last through a ton of use. The specs are precise: 9mm inside diameter (ID), 15mm outside diameter (OD), and 20mm in length. What's really cool is the concentricity (how centered the hole is) is held to an incredibly tight tolerance – we're talking 0 to .0003 T.I.R. maximum for this size. That precision is key for accurate drilling and longer tool life. They've also added a blended radius at the drill entrance. This isn't just for looks; it actually helps guide the drill in smoother, improves alignment, and seriously cuts down on tool wear and breakage. Less frustration, more drilling. It's a no-counterbore design, and the ID tolerance is +.0001/.0005. Everything is made to exacting standards. Plus, you can feel good using it – it's free of any conflict materials and conforms to REACH standards. So whether you're in a professional machine shop or a serious home workshop, this bushing gives you that perfect blend of American-made quality, precision engineering, and durability that just works.
