werkzeugtechnik product ADVANTAGES Special milling cutters are increasingly used for the manufacture of complex forms, as a time-consuming adjustment of the individual form segments is no longer

Thereby setting times can be reduced and a 100% dimensional accuracy can be guaranteed throughout the complete tool-life, especially after a repeated re-grinding of the tooth face.

standard milling cutters. As a result, productivity on the whole as well as the surface quality of the work piece can be increased.

3 werkzeugtechnik product ADVANTAGES Special milling cutters are increasingly used for the manufacture of complex forms, as a time-consuming adjustment of the individual form segments is no longer necessary. The form milling cutter combines, if technologically possible, the complete form of a work piece. Thereby setting times can be reduced and a 100% dimensional accuracy can be guaranteed throughout the complete tool-life, especially after a repeated re-grinding of the tooth face. Spur-toothed, as well as spiral-toothed milling cutters, supplied as relief-turned or logarithmical relief- ground versions, can be manufactured with substantially more teeth numbers compared to standard milling cutters. As a result, productivity on the whole as well as the surface quality of the work piece can be increased.

Whether the material is stainless steel, or the application requires an extremely sharp cutting edge or maybe a specific diameter and length is required: it is here, where we see our main strength and how our customers benefit from the highest quality standards through years of experience in supplying drilling and milling tools. We can supply small batch series, individual parts, components, finished parts and complete sets everything according to the customer s specifications and preference. 3

serration and gear tooth cutters Serration cutters are designed with parallel offset rows of teeth. Single milling slots on the work piece are not necessary anymore.

The cutters are especially suitable for the interconnected gear tooth forming of mouth parts on surgical instruments.

4 serration and gear tooth cutters Serration cutters are designed with parallel offset rows of teeth. Single milling slots on the work piece are not necessary anymore. Cutters with logarithmically relief grinding retain a constant profile form until the cutter is completely used up. The cutters are especially suitable for the interconnected gear tooth forming of mouth parts on surgical instruments.

18 step drills Due to their special characteristics, step drills allow an economic production. From the simple core hole drill up to the complex subland twist with multiple twists and form passages, the drilling tools can be adjusted in their core thickness and in the chips space to the exact diameter proportion. This is their main advantage, as this precise adjustment is not possible with DINtools. Step drills are always manufactured according to drawing or a sample. They are available with parallel, reduced or conical shank and with addressing thread or clamping surface. With any tool type a highly economic processing is facilitated as several processing steps can be combined to one.
