Solutions for cost effective and high-quality machining of oil and gas spool body features
A spool body is part of a subsea oil and gas production tree. The component is part of the tree assembly that helps monitor and control the production of a subsea well, it can also manage fluids or gas injected into the well.
Its main function is to control flow from the wellbore. It also provides outlets to attach several different configurations of valves.

Tooling solutions for machining of oil and gas – spool body features
CoroMill® MS20 – open and closed pocket milling, full slotting, hole making (helical ramping)
- Use M-M20 geometry for excellent chip formation and evacuation in sticky materials
- M-M30 geometry gives higher security in tougher materials (duplex). Higher edge line toughness of the geometry allows the insert to be used with higher productivity (high cutting data) in stable operations
- Use E-L50 geometry for long overhang applications where a sharper and hence lighter cutting edge will help reduce vibrations
- Robust steel shank design ensures better stability and less deflection
- The two cutting edges have equal tool life and the M-M20 geometry provides predictable and gradual wear characteristics, especially in austenitic stainless steel
PrimeTurning™ - all directional turning with extraordinary productivity for internal and external turning applications
With the CoroTurn® Prime SL head solution it is now possible to use our PrimeTurning™ methodology for internal turning. The inside-out machining capability allows for excellent chip evacuation and chip control.
Silent Tools™ - Overcome vibrations when machining long overhangs
To keep chips flying at a high rate, it is important to reduce vibration as much as possible. Silent Tools™ dampened boring bars minimize vibrations. In this way, a high metal removal rate is possible.
CoroTurn® SL adaptor interface
CoroTurn® SL is a modular system of adaptors and cutting heads with which you can build customized tools for a variety of turning applications with a minimum amount of items. The robust coupling and many combination possibilities makes it ultimate for building a tool for machining complex components.
CoroBore® BR30
Three-edge rough boring tools for maximum productivity. Very productive multi-edge tool, available from three to eight cutting edges, for maximum metal removal rate.
Rough boring tools
Roughing is primarily focused on metal removal and is performed to open up an existing hole made by methods such as pre-machining, casting or forging. Rough boring prepares the hole for finishing.
Coromant Capto® is a modular quick-change tooling concept offering three systems in one. Benefits with Coromant Capto® are:
- Flexible with extensive modularity
- High basic stability and accuracy
- Minimized tool inventory
- Reduced set-up time
Coromant Capto® Plus – Predictive maintenance
With Coromant Capto® Plus you can predict the maintenance need of your driven tool holder and plan accordingly.
CoroCut® 1-2 - Versatile parting and grooving
With more than 700 standard inserts, CoroCut 1-2 covers all parting and grooving applications in most materials, from standardized grooves to parting off and profiling in heat resistant super alloys.
CoroMill® MH20
High-feed milling cutter optimized for:
- Open and closed pocket milling
- Full slotting and hole making with helical ramping cycles
- Long overhang cavity milling
- Low engagement shoulder milling
- Multi-task turn milling
