Drill Combines Modular, Solid Carbide Characteristics
Available over a standard diameter range of 0.3150" to 0.8264" (8 to 20.99 mm) and at length-to-diameter ratios of 3×D and 5×D, drill bodies are available in either flanged-shank (metric) or round-shank (inch) configurations. They feature solid coupling for consistent performance from insert to insert, and a front-clamping mechanism is said to ease insert changes.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
