CHAMDRILLJET - Holder Variety
CHAMDRILLJET drill bodies are available in the diameter range of 8 to 25.0 mm, in whole sizes. Their drilling depth-to-diameter ratios is 1.5XD, 3XD and 5XD. All drill bodies have helical internal coolant holes that coincide with the holes in the drill heads for most efficient cutting edge cooling and chip evacuation. Shank characteristics are identical to the original CHAMDRILL family.
CHAMDRILLJET drill bodies have a 30° flute helix that coincides with the drill heads. This system provides excellent hole accuracy, straightness, surface finish and chip evacuation.
Note: CHAMDRILLJET is not interchangeable with the original CHAMDRILL system.
