Festool GM 145 Die Set / Guide Frame for CM 150
At a Glance: Guide frame for the Festool CM 150 chain mortiser, designed for accurate mortising with depth stop, side stop and pneumatic spring-assisted plunge control.
The Festool GM 145 die set, also known as the GM 145 guide frame, is a specialist accessory for the Festool CM 150 chain mortiser. It is designed to guide the chain mortiser securely during heavy-duty timber mortising work, helping the user create accurate, repeatable mortices and grooves in beams, structural timber and carpentry components. With precise depth and distance setting, machined steel vertical guide rods, a side stop and pneumatic spring-assisted plunge and retraction, the GM 145 gives the CM 150 a more controlled and repeatable mortising setup for professional timber construction and joinery work.
The GM 145 is built for users who need clean, repeatable mortices rather than rough freehand chain mortising. It supports accurate plunge movement, safer retraction and repeat settings when creating several identical mortices or grooves.
Product highlights
- Designed for the CM 150 Built for secure guidance of the Festool CM 150 chain mortiser.
- Accurate mortising support Helps create precise, repeatable mortices and grooves in timber.
- Pneumatic spring-assisted movement Supports smooth, controlled plunge cutting and retraction.
- Machined steel vertical guide rods Help keep plunge movement precise and stable.
- Depth stop included Allows controlled setting of mortising depth.
- Side stop included Helps position the mortise accurately from the edge of the workpiece.
- Adjustable lateral fence Fence can be variably adjusted from 5 - 150 mm.
- Repeat work made easier Ideal for creating several identical mortices or grooves.
Extra Information
- The GM 145 is an accessory for the Festool CM 150 chain mortiser.
- It is intended for mortising applications using compatible mortise chain sets.
- The guide stand supports mortise chain sets from 100 - 150 mm long for the CM 150.
- The lateral fence is variably adjustable from 5 - 150 mm.
- The system is especially useful where several identical mortices or grooves need to be created accurately.
- This product is the guide frame / die set accessory and does not include the CM 150 chain mortiser itself.
Pro Tips
- Set up and test the mortise depth on scrap timber before cutting finished structural pieces.
- Mark the mortise centreline and reference edge clearly before clamping or positioning the guide frame.
- Use the side stop for repeat work so matching mortices are positioned consistently.
- Keep the guide rods clean and free from resin, chips and dust to maintain smooth plunge movement.
- Check the chain, guide bar and chain lubrication before starting heavy timber mortising work.
How to Use
- Confirm that the Festool CM 150 chain mortiser and mortise chain set are compatible with the GM 145 guide frame.
- Mount the CM 150 chain mortiser securely onto the GM 145 according to the Festool instructions.
- Mark the mortise position, centreline and reference edge on the timber.
- Set the lateral fence according to the required distance from the workpiece edge.
- Set the required mortising depth using the depth stop.
- Position the guide frame securely on the timber before starting the mortising operation.
- Start the chain mortiser and allow it to reach operating speed.
- Plunge the machine smoothly using the guided movement of the GM 145.
- Allow the pneumatic spring-assisted retraction to help return the machine safely after the cut.
- Switch off the machine and wait for the chain to stop completely before repositioning or making adjustments.
Features
- Guide frame construction Provides stable support and guidance for the CM 150 chain mortiser.
- Precision guide rods Machined steel vertical guide rods assist with accurate plunge and retraction movement.
- Integrated gas spring support Helps make plunge cutting and retraction smoother and safer.
- Adjustable depth setting Allows mortising depth to be controlled for repeatable results.
- Adjustable side stop Helps maintain consistent mortise positioning from the workpiece edge.
- Easy machine mounting Designed for straightforward mounting of the chain mortiser.
- Mortise chain compatibility Suitable for use with 100 - 150 mm long mortise chain sets for the CM 150.
Benefits
- More accurate mortices: The guide frame helps control plunge movement and workpiece positioning for cleaner, more consistent mortising.
- Better repeatability: Depth and side-stop settings make it easier to produce several matching mortices or grooves.
- Improved control: Pneumatic spring support and steel guide rods help the machine move smoothly during plunge and retraction.
- Professional timber framing support: Ideal for users working with beams, structural timber and heavy carpentry joints.
- Safer handling: A guided setup helps reduce the instability and guesswork of unsupported chain mortising.
Application
- Mortising with the Festool CM 150 chain mortiser.
- Creating mortices in beams and structural timber.
- Producing repeat mortices for timber framing work.
- Creating grooves or recesses where controlled plunge guidance is required.
- Setting consistent mortising depths and distances.
- Carpentry, roof truss work, timber construction and renovation applications.
- Professional on-site and workshop timber joint preparation.
Safety
- Wear suitable eye, ear, hand and dust protection when mortising timber.
- Use only with the compatible Festool CM 150 chain mortiser and suitable mortise chain sets.
- Make sure the chain mortiser is correctly mounted and secured to the guide frame before use.
- Check that the depth stop and side stop are firmly set before starting the cut.
- Secure the timber properly so it cannot move during the mortising operation.
- Keep hands clear of the chain, guide bar and mortise opening at all times.
- Do not force the chain mortiser into the timber; use controlled plunge movement.
- Allow the chain to stop completely before lifting, repositioning or adjusting the tool.
- Disconnect the machine from power before fitting, removing, adjusting or cleaning the guide frame.
- Inspect the chain, guide bar, stops and guide rods before use and do not operate damaged equipment.
