System-One offers the first real advance in 50 years of drill and tapping cast iron and steel. The system combines specially
designed high speed Machine Steel Taps with a range of Fine Tolerance Holesaws on a single cutting shaft, that does not require
a pilot drill. The combination ensures the minimum amount of metal is cut and the speed of the cut is increased dramatically
without compromising accuracy.

HOLESAWS
- Holesaws cut cast iron and steel at high speed through to 2½" diameter.
- High level of accuracy while inexpensive to replace.
- Designed for hand or powered operations.
- Magnetic coupon retention system.
TAPS
- No power is required for taps on cast iron or steel to 2½" diameter.
- Skip-tooth design eliminates unreasonable tapping force on larger sizes.
- Tap depth sets automatically.
- Tap follows Holesaw in a single operation.
- Unequalled accuracy and thread quality.

Hand tapping in cast iron always produces a significantly better thread form, but often results in excessive tapping loads.
To solve this, the System-One has specially engineered the larger taps with a Skip-tooth design that reduces the load by half yet is capable of producing an extremely high quality thread form by hand.
- Cheater bars are never required, even when cutting a 2½" taper with a course 8 threads per inch.
- Taps are loaded onto the drill shaft behind the holesaw cutter so changeover time is eliminated.
- The result is a completed 2½" drill and tap in cast iron in seven minutes or less.
