- Three flatted shank design provides better chuck grip and reduces slippage, ideal for use in keyless chucks
- High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and non-ferrous materials
- Oxide coating prevents chip building, galling and welding on the workpiece
- Round shanks with flats are ground flat on three sides for increased chuck grip, reducing slippage and help centering the drill in the chuck
- All silver and deming bits are 6 in long and feature a 1/2 in reduced shank that fits all 1/2 in drills
- Engineered with premium high speed steel with black oxide coating for corrosion resistance
- They are used with portable drills and drill presses on ferrous and non-ferrous materials
- 118 deg chisel point tip is perfect for general purpose applications

Browning® 1293455 Riveted Standard Duty Roller Chain, 10 ft OAL, 3/8 in Pitch, 0.2 in Dia x 3/16 in W Roller, Steel
All Browning® ANSI B29.1 roller chain is prestressed, a production operation that permanently seats the various chain components. Prestressing minimizes the chain stretch which often occurs with ordinary chain during the initial running period, thus avoids excessive early wear and reduces the need for take-up adjustment. Prestressing minimizes tolerance variations too, ensuring balanced loading among all parts and avoiding premature fatigue failure.
