Application & selection

Carbide rods are used as material for drills, end mills, reamers and other cutting or wear components. The supplied carbide notes describe rod selection in terms of wear resistance, toughness and the requirements of subsequent tool manufacture.

For a tool blank, specify diameter, length, finish and grinding allowance together. Coolant-hole geometry, straightness and the intended tool operation should be agreed on the drawing before the final grade and dimensions are confirmed.

Details to confirm for this product

• Diameter, length, straightness and dimensional tolerances.
• As-sintered or ground condition and remaining machining allowance.
• Solid or coolant-hole design, tool application and grade requirements.
