Product Specification

#3 X 6" SQUARE INSERT BIT 1/4" HEX - 10 PACK

Benchmark Abrasives #3 x 6" Square Insert Bit 1/4" hex are CNC machine ground out of heat-treated S2 Shock resistant tool steel, which will withstand extremely high torque output and provide maximum durability.  They are widely used on electric screwdrivers, hand screwdrivers, cordless drills, etc.

Square bits are also known as Robertson bits. The tip geometry of the Square Insert Bits reduces wear and creates an ideal fit with every fastener. This square insert bit is used in mortising machines or drill presses. They are used in hand drivers or with a bit adapter in power tools. It features a unique torsion zone to deliver long life in both metal and wood fastening applications. They are engineered with heavy-duty, cold-forged, high-grade steel to withstand high torque output and are built for maximum durability and long life with impact drivers.

Jason J. ★★★★★

Finally got these to replace my worn-out stubby bits, and the CNC grinding is noticeable — they grab screws much tighter than my old ones. The extra length is great for deep-set hardware, and a 10-pack means I won't run out anytime soon.

Ryan F. ★★★★★

These bits held up perfectly driving hundreds of screws into hardwood, and the 6-inch length gave me plenty of reach in tight spots. The CNC-ground tip grabbed the fastener heads without any slipping or stripping.

Natalie Q. ★★★★★

I needed longer bits for a deep-set deck screw, and these 6-inch square drives reach perfectly without wobbling. All ten bits feel precisely ground and fit snugly into my impact driver.
