Coolant Fed - Blind Hole
Internal coolant channels direct the cutting fluid directly to the cutting zone. Pressurized coolant helps cool the tool and workpiece while adding in chip evacuation. There are two types of coolant channel designs:
- IKZ - Internal coolant-lubricant supply, axial (DIN designation: KA). The axial exit of coolant-lubricant provides optimum cooling and lubrication in the chamfer area. Chips are evacuated easily from blind holes.
- IKZN - Internal coolant-lubricant supply, axial, with coolant exiting in the flutes (DIN designation: KR). Radial exit of coolant-lubricant is the safest solution for providing coolant-lubricant supply in the chamfer area even in through holes.
