CARBIDE OPERATIONAL GUIDANCE Drill Holding Through Coolant Type Spindles Revolving Through Coolant Coolant Type Machine Type Coolant pressure is approx. 0.5MPa 7MPa Stepped Holes Divide the two processes. Drill the larger hole first. Atool for machining both chamfer and spot face can be produced to order. Drill Length A DC x 1.5 Coolant Handling 1) Small particles of swarf will jam in the oil hole of small diameter drills. Always use a fine mesh filter as a preventative measure. 2) Dirt and dust particles adhere to the oil in old coolant and prevent an efficient flow. Regular coolant exchange is recommended. Interrupted Cutting TL u One Process O Lower the feed when drilling the interrupted part. Requires Prior Machining A Spot face with an end mill prior to drilling.
