I-R BRINGS OUT CUPS
The Rock Drill division of Ingersoll-Rand has added button bit
resharpening cups to its range of drilling accessory products. The
grinding cups have been field tested under the severest conditions
and have proven to be an excellent tool for extending the life of
all types of threaded accessories and down-the-hole drill
bits.
The cups can be attached to hand-held air-powered reconditioning
grinders from I-R and all other major brands of bit grinder
designed for use with cup type wheels. They are available in
button, body and combo designs for spherical (standard) carbides
and there is also a design for sharpening ballistic carbides.
