Our holesaws have a corrugated edge which provides extra cutting clearance for speed of drilling and also good core ejection. These holesaws are used with a standard 1/4" pilot drill (not included). An optional ejector spring is available. Special size holesaws available upon request.
Auto ejection holesaw will automatically eject FRP cores as quickly as holes are drilled. This unique holesaw was designed for use in a fixture for production drilling. Prices upon request.
