(5) Designed for maximum performance
and hole cleaning ability and high penetration rate.Our bits are
interchangeable with Atlas Copcos COP*2 *4 *4 *4 *4 *4,

(6) Matching the insert to the job
requirements is essential in achieving the desired results. Each of
the following buttons is ideal for different ground conditions,
abrasion levels, PSIs and penetration levels. In general, the
larger the number of gauge buttons the better overall performance,
especially in hard rock.
