SPOOL BORE HOLE
Ring-free machining.
Machining spool bore holes in hydraulic valve bodies, hydraulic pumps etc. in cast iron often involves a number of challenges in the machining process.
Our self-developed 3-way solution which consists of pilot drill, ring-free reamer and UM grooving land tool has the following benefits:
- A straight hole free of rings
- Excellent size consistency
- Huge cycle-time reduction normally up to 50%
- Optimised tolerances

Watch our self-developed 3-way solution to machine spool bore holes faster and with more consistency.
Our solution consists of a pilot drill, a ring-free reamer and the UM grooving land tool.
1. Pilot drill
- Pre-machine for further precision
- Spotface can be added
- Different steps for threads possible to reduce the total machine time
2. Ring-free reamer
- Eliminates any rings during reaming, so no manual handling getting the rings out is neccesary which can be very time consuming/difficult work
- The tiny chips are flushed out at the end leaving the workpiece ready for the grooving land tool
3. UM Grooving land tool
- One-shot solution which can reduce the machine time by as much as 70%
- Tight tolerances are built into the tool for more precise machining
- Designed to avoid vibrations, making it more reliable
- Can be used in cast iron, aluminium and steel materials
