Description of Milwaukee 48 20 8840 Hammer Drill 6 Inch
Fast drilling. Long life. 3-Flat Secure-Grip prevents bit from slipping in the chuck. Comprehensive offering with diameters from 1/8 in. to 1 in. with lengths up to 18 in.
This industrial drill bit is definitely not worth the investment.I found that it struggled to punch through even moderately tough materials, leaving me frustrated and out of pocket..
