Notes on Drilling 1. Step feeding or pecking is required for drilling greater than 3 x Ø. 2. When drilling cast surface & black( ie: not machined surface), reduce drilling speed by 20 %. 3. For optimal positional accuracy and hole size, the use of spot drills is recommended prior to drilling desired hole, refer to our standard range( D175). 4. For hole depths greater than 7 x Ø, pre-drill initially to pilot start for more accurate hole position and eliminate drill wandering. The pilot can be drilled with short rigid drill, approx. 3 x Ø in depth and reduced feed to ensure accurate pilot hole.
