Speeds and feeds are based on using soluble oil where applicable 1:5 to 1:10 concentration. 2. When other than an end mill collet is used, make sure the drill shank is firmly attached. 3. For deep holes (4 times the drill diameter or deeper) use the lower recommended feed rate as a starting point and increase as needed for the best result. 4. Recommended feeds and speeds are starting points only. Actual performance will be determined by specific material, the condition of equipment being used, and coolant.
