Bit Catcher

Bit Catcher

Broken bits can cost a great deal in time, efficiency, and revenue; but the Halco Bit Catcher System prevents the need for the added time and expense of difficult "fishing" procedures to save the hole.

Designed to fit a wide range of Halco’s class leading standard down the hole hammers, the Bit Catcher System provides an effective retention method should the drill bit break in its most susceptible area, above the head of the bit. If a breakage occurs in this area, the head of the bit is retained within the Bit Catcher System and not lost down the hole.

The Halco Bit Catcher System uses a specially designed Chuck and Drill Bit arrangement to ensure there is no loss of drilling performance from either the hammer or the Drill Bit, while providing the driller with peace of mind and reassurance that should a breakage occur the Drill Bit will be securely retained within the catcher system.
