FAQ's

What is a tool grinder?

A tool grinder sharpens and re-grinds cutting tools such as end mills, drills, reamers, countersinks and saw blades. It restores the cutting edges and thereby extends the service life of the tools.

Which tools can I sharpen with a tool grinder?

Typical tools are end mills, drills, step drills, taps, reamers, countersinks, step and form tools, lathe tools, gravers and saw blades. Exactly which tools are possible depends on the machine and its equipment.

What is a universal tool and cutter grinder?

A universal tool and cutter grinder covers many grinding tasks on one machine. With internal and external grinding attachments it is suitable for sharpening tools and for light cylindrical and surface grinding. That is practical for shops with changing tasks.

Does KNUTH offer CNC tool grinders?

The focus of the KNUTH lineup is on compact and universal tool grinders. For batches with programmable, repeatable grinding cycles we advise you on the right solution. Send us your requirement and we will find the suitable machine.

Which grinding wheel do I need for carbide or HSS?

For HSS and hardened steels, CBN is suitable; for carbide, diamond. Corundum is the versatile classic for many standard tasks. The wheel is always matched to the tool material.

Should I buy a tool grinder new or used?

KNUTH supplies new machines with warranty, advice and service. Used machines are cheaper but often bring unknown wear and no manufacturer support. For continuous operation, a new machine is usually the more economical choice.

Who benefits from having their own tool grinder?

Production shops, toolmaking, maintenance and training operations. Anyone who uses tools regularly saves tooling costs through re-grinding and stays independent of outside grinding services.

What is the difference between tool grinding and surface or cylindrical grinding?

Tool grinding works on the cutting edges of machining tools. Surface and cylindrical grinding work on part surfaces. For those tasks KNUTH offers conventional grinding machines as well as belt and disc sanders.

How quickly is a tool grinder available?

Many machines are available from stock at short notice. The exact delivery time depends on the model and equipment. Ask about availability for your preferred machine directly.

Does KNUTH offer advice and service for tool grinders?

Yes. We advise on the machine, grinding wheels and accessories, handle commissioning and training, and offer repair and spare parts service through our Americas team. That keeps your machine ready for operation over the long term.

Tool grinders for sharp, long-lasting tools

A tool grinder restores the original cutting quality of your machining tools. Instead of replacing dull tools, you re-grind them and extend their service life considerably. This lowers tooling costs and keeps the machining quality of your parts consistent. KNUTH supplies tool and cutter grinders for production, toolmaking, maintenance and technical training.

Which tools can be ground?

Tool grinders handle a broad range of cutting tools. Typical applications include:

End mills in HSS and carbide
Drills and step drills
Taps and reamers
Countersinks as well as step and form tools
Lathe tools and gravers
Saw blades and further cutting tools

Precise re-grinding of the cutting edges makes the tools cut cleanly again and helps you avoid scrap caused by dull edges.

Types of tool grinder

Different designs suit different shops and tasks:

Compact bench and shop machines for small shops, maintenance and training. An affordable entry point, ready to use quickly.
Universal tool and cutter grinders for changing tasks. With internal and external grinding attachments they cover tool sharpening and light cylindrical and surface grinding.
CNC and programmable tool grinders for repeat batches and complex tool geometries with high repeatability.

Which design fits depends on your parts, batch sizes and the experience of your operators.

Grinding wheels: CBN, diamond and corundum

The grinding wheel is matched to the tool material:

CBN (cubic boron nitride): for HSS and other hardened steels.
Diamond: for carbide and very hard materials.
Corundum: the versatile classic for many standard tasks.

The right wheel ensures clean cutting edges, low wear and economical grinding.

Manual, universal or CNC: which tool grinder fits?

For individual repairs, maintenance and training, a compact, manually operated tool grinder offers the most affordable entry. If you sharpen many different tools, a universal machine is more flexible. For repeat batches and consistent precision, programmable CNC cycles pay off. If you are unsure, a KNUTH specialist matches the machine to your tools, your materials such as HSS or carbide, and your batch sizes.
