Tungsten Carbide Drill Bit R38 Thread Mining Drill Bits with Flat
Face and 14 Ballistic Insert Buttons
Product Description:
Semi-dome bits are designed for fast penetration rates in softer
rock like shale and limestone with low silica content.
Drop Center bits will help drill straighter holes in less
consolidated rock.
Flat Face bits are a general purpose bit that will perform in all
rock conditions but should be used especially for hard or abrasive
conditions like granite, basalt, and hard limestone. Flat face bits
are the best choice for drilling in abrasive rock.
