Concrete Planer Accessories — Drums, TCT Cutters and Diamond Cutters

A concrete planer removes and levels a concrete or asphalt surface using a rotating cutter drum — a cylinder fitted with cutting elements. The three main accessory groups are: a complete cutter drum (a ready-to-fit assembly for a full replacement), individual tungsten carbide teeth (TCT) — hard tungsten-cobalt tips on a steel shank — and diamond cutters for thinner, more precise passes. These are components for professional planing machines, not a substitute for core bits used with an ordinary drill — the two differ in construction and purpose.

At NORWIT.PL we stock accessories fitted primarily to planers from Hemming Technik, Toolsa and Husqvarna Construction, and the machines themselves are listed under concrete planers. Hemming Technik drums and cutters also fit that brand's underfloor heating planers (used for cutting grooves for heating pipes) — the full range is on the Hemming Technik page. Below: the difference between TCT and diamond cutters, and how to match a drum to your model.

Types of Planer Accessories — Drum, Cutters, Diamond Tools

We organise the range by the form of the part sold. A complete cutter drum is replaced as a whole once the old body is worn or damaged, while individual cutters and teeth let you service an existing drum without buying a new assembly. Diamond cutters are a separate category, used where precision matters more than raw removal speed.

Looking for a drum for a Toolsa planer, or a full set of TCT cutters for a Husqvarna planer? Selection starts with the machine model — drums and cutters are engineered for a specific tooth-holder system and working width, so a part from another brand usually won't fit without checking the product page.

Tungsten Carbide Teeth (TCT) vs Diamond Cutters

TCT teeth have a tip made of tungsten carbide — a hard tungsten-cobalt alloy — fixed to a steel shank driven into the drum body. They work by impact, cutting and chipping away material, so a single pass can remove a layer several millimetres thick of concrete, asphalt or an old coating. A drum typically carries a dozen to several dozen teeth arranged in a spiral pattern.

A diamond cutter works differently — a segment set with synthetic diamond grinds the material finely and removes a thinner layer (fractions of a millimetre up to roughly 1–2 mm per pass), leaving a smoother surface and coping better with hard aggregate. Diamond cutters suit precise levelling ahead of coatings, while TCT teeth suit quickly removing a thicker layer.

Matching a Drum to the Planer Model — Hemming Technik, Toolsa, Husqvarna Construction

A drum and its cutters are matched to a specific model, not chosen by eye — the deciding factors are working width (200–350 mm on floor planers) and the tooth-mounting system, which differs between manufacturers. A part designed for one brand usually won't fit another.

Before ordering, note down the brand, model and drum width from the nameplate — we'll match a set dedicated to your machine, not a universal substitute.

When to Replace Cutters and How to Maintain a Planer Drum

A TCT tooth signals wear through visible wear of the carbide tip, reduced output at the same downward pressure, and an uneven finish on the surface. On hard aggregate a set wears out faster than on soft concrete; as a rough guide, a set lasts tens to hundreds of square metres of planed surface. Delaying replacement overloads the remaining sound teeth and accelerates drum wear. Clean the drum of dust and store it in a dry place — moisture corrodes the mounting shanks — and check the teeth are tight every few to a dozen or so shifts; play increases vibration, and even one missing tooth throws off the cut.
