efficiency and mining costs associated with drilling.
Brady's Ceramic Rotary drill bits now out perform carbide percussion drill
bits in many HARD ROCK drilling applications such as roof drilling, tunnel
drilling and bench drilling. Formations of limestone, salt, shale, gypsum,
porphyry copper, lead-zinc, gold and platinum deposits are easily drilled with
Rotary drills and Brady's Ceramic drill bits. Brady's Ceramic drill bits are
capable of drilling very very hard, 36,000 psi compressive strength high
silica formations.
Brady's Ceramic Rotary drill bits reduce NOISE levels by 20 to 40 db's over
drilling with percussion drills and carbide bits.
Brady's Ceramic rotary drill bits can be used with 100% water or an Air
mist drilling system. Water volume may be reduced from a flow rate of 12-15
gpm to 1-3 quarts/min. in mines where high water volume is not desirable, by
using the Brady Air-Mist Drilling system and Ceramic drill bits.
Brady's Ceramic Rotary drill bits have proven to be very effective for Tunnel
and Bench drilling applications. Less drill maintainence, faster penetration
rates and longer bit life with Brady Ceramic drill bits, improves mine production.
Brady's Ceramic Rotary drill bits are cost effective, outlast carbide bits by
100 to 300 times, require no re-sharpening and reduce noise and respirable
dust levels substantially.
Brady's Ceramic Bits are available for Roof drilling, Tunnel drilling and Bench
drilling. For more information on "Drilling With Ceramic Drill Bits" contact
