16mm Drill Groove Cutter HSS-Co8 TiCN Coated 3-Flute Long Weldon Shank, DIN 844 - TECWERK

Take advantage of the combination of HSS‑Co8 material, TiCN coating and a Weldon shank for high durability, reliable clamping and consistent slotting performance; order the TECWERK slot drill directly via Metav Werkzeuge or consult our specialists for tailored advice.

TECWERK Slot Drill DIN 844 Type N – Ø16 mm, HSS‑Co8, TiCN Coating

The TECWERK Slot Drill DIN 844 Type N is a long, centre‑cutting end mill engineered for precision slotting and plunge milling in steels and stainless steels on manual and CNC machines.

• TiCN coating for longer tool life
• HSS‑Co8 grade for high‑temperature strength
• Weldon shank with drive flat
• Centre‑cutting 3‑flute long design

Reliable cutting performance where it counts

Built from HSS‑Co8, this long centre‑cut end mill provides enhanced hot‑hardness and fracture resistance compared with standard high‑speed steels, translating into longer cutting intervals and fewer tool changes. The Ø16 mm shank and robust body support steady chip evacuation during slotting, while the three‑cutting‑edge geometry delivers a balance between material removal rate and surface finish. For production environments aiming to reduce non‑productive time, the material choice and flute configuration are a practical investment in process stability.

Coating that extends tool life for industrial runs

The TiCN coating improves wear resistance and reduces built‑up edge, especially when machining abrasive stainless steels and cast iron. Applied to the cutting zones, the coating enables higher cutting speeds with retained edge integrity, which is particularly advantageous in longer runs and batch work. Centre‑cut capability allows safe plunge entry; combined with the coating, it helps maintain consistent tolerances throughout repeated operations and reduces the need for frequent regrinding.

Secure clamping and vibration reduction for accurate slots

A Weldon shank with drive flat ensures positive axial drive and prevents rotation in collets or chuck systems, promoting concentricity and repeatable slot width. The tool’s long design, together with the specified effective length 42 mm, supports deeper slotting applications while the right‑hand cutting geometry offers conventional chip flow for many CNC and manual milling setups. Proper clamping and the solid shank reduce chatter and improve surface integrity, giving measurable gains in first‑pass component acceptance.

Material suitability and machining guidance

This cutter is specified for machining a broad range of materials: very good suitability for steels, stainless steel and cast iron, with conditional suitability for non‑ferrous alloys and special alloys. The three flutes favour improved cutting stability at moderate feed rates and help maintain a steady chip load in slotting operations. For best results, select feeds and speeds according to workpiece hardness; the combination of centre‑cutting design and TiCN coating makes the tool suitable for light plunge cuts and finishing passes where surface quality is important.

FAQ

What materials can this slot drill machine reliably cut?
The TECWERK slot drill is rated very good for steels, stainless steel and cast iron, with conditional suitability for non‑ferrous and special alloys, making it versatile for general workshop and industrial use.

Is the tool suitable for plunge cutting or only side milling?
Yes. The centre‑cutting geometry allows plunge entries; paired with the TiCN coating and HSS‑Co8 material, the cutter supports controlled plunge cuts for slotting and pocketing operations.

How does the Weldon shank benefit machining stability?
The Weldon shank with drive flat prevents rotation in the toolholder and improves clamping security, which reduces run‑out and vibration during slotting with the Ø16 mm shank.

How many flutes does the cutter have and what is the effect?
The cutter has three flutes, which offer a compromise between chip clearance and cutting stability, suitable for slotting where balanced material removal and surface finish are required.
