Using LHS Rotary Percussion Core Bits (Fig. 9-12)

LHS Core Bits are useful for drilling large or long holes in concrete. MILWAUKEE Heavy-Duty Core Bits have heat-treated steel bodies with durable carbide tips. These core bits are specially designed for fast, accurate drilling with combined hammering and rotary action.

1.Clean and lubricate the threads on the adapter and core bit to make later removal easier. Screw the threaded end of the centering bit into the core bit (Fig. 9). Thread the adapter shank to the rear of the core bit.

NOTE: If using an extension, first thread the adapter shank to the extension. Then thread the core bit to the extension.

NOTE: To make deeper holes, remove the core bit, break and remove the core. Resume drilling. When drilling long or deep holes, after each inch of penetration pull the bit partially out of the hole while the tool is running, to help clear dust from the bit flutes. Dust can clog the bit flutes and can make the bit bind in the hole. If this occurs, stop the tool, free the bit and begin again.
