DURABIT®1 tool bits are designed to run at high RPM. Run all the Tri Tool® Model 300 Series squaring machines at full speed. Do not "dive" the bit into the work. Make sure that when starting the cut on interrupted or out-of-square ends, you advance the tool bit slowly against the tube end with light feed pressure until a continuous chip is achieved (bit cuts all the way around end). Once the bit has a full chip load, use a moderate to heavy feed pressure to finish the cut. NEVER stop the tool bit while in the cut. Back the bit away from the cut at full speed and then you can stop the motor. These instructions also apply for Durabit 2 and 3 bits.

Tool Bit Resharpening Policy

Tool bits must be received in a condition which will allow Tri Tool Inc. to resharpen them. Badly gouged, chipped or broken tool bits cannot be resharpened cost effectively. Tool bits will be evaluated upon receipt, and the customer will be contacted for authorization within two working days. The customer will be furnished a price and scheduled return shipment date. The price structure is available from your Tri Tool sales representative. Tool bits which are not suitable for resharpening will be returned, along with those bits that could be resharpened, unless Tri Tool Inc. is instructed otherwise. Shipping charges to and from Tri Tool are the customer's responsibility. Only tool bits manufactured by Tri Tool are covered by this policy.
