Vc: Cutting speed (m/min), f: Feed Rate (mm/rev) Recommended Drilling Method 1. Drill a pilot hole using the dedicated PHT Select the same nominal diameter for the dedicated pilot hole drill PHT type as the deep hole drill XHGS type. (The pilot drill diameter is designed +0,02mm to +0,05mm larger than the long drill diameter) 2Enter the pilot hole at reduced cutting data Rotation speed: 500min-1, Feed rate: 1000 to 2000mm/min Stop 1mm away from the pilot hole depth Important: DO NOT enter pilot hole at higher cutting data, this will cause damage to the drill. 3. Increase rotation speed until the set cutting speed is reached, and start normal drilling operation Increase rotation speed When using a NC machine, only begin drilling operation once full rotation speed is reached. 4. After drilling rotation speed is reduced and the drill is retracted from the work material Rotation speed: 500min-1 Feed rate: 1.000 to 2.000mm/min Retracting a drill from the work material at a high rotation speed is dangerous as doing so may result in breakage due to run-out. 5. Other Notes A flat base should be prepared when the surface for the pilot tool is slanted. Spot face using: 0 0 MultiDrill MDF type Flat endmill When the deep hole drill exits through an angle surface, decrease the feed rate to f=0,05mm/rev just before drilling through. Coolant 1. Internal coolant supply Use suitable coolant / emulsion Pump pressure: Steel: 1,5 to 2,0MPa (cooling effect increases at higher pressure, affecting chips/wear) Cast iron & aluminium alloy: 4,0 to 6,0MPa (priority on cooling) 2. Internal MQL Airpressure: 0,5MPa or higher Discharge volume: It is recommended to set the maximum discharge volume possible on the machine. Consult the manufacturer before using with aluminium alloy. Change the rotation speed to 500min-1 K37 Multi-Drills
