48005261

TCT TORCH 150mm x 7 Tpi - 1 pc

Carbide-tipped teeth ensure longer life in heavy-duty applications. Up to 50 times longer lasting than bi-metal blades.

Sturdy 1.27 mm thick body for precise straight cuts.

25 mm blade height for greater stability and less vibration.

Ideal for demolition of cast iron and all thick metals.

Universal blade Bosch 2609256974 AIZ 28 SC HCS 28×50 mm, HCS (High Carbon Steel) accessory for multi-tools (OIS/PMF), ideal for cutting grout, wood, plastic and soft materials with compact dimensions for precision and versatility.

Step drill bits are ideal for drilling the following materials: - Ferrous and non-ferrous sheet metal, profiles and tubes. - Copper, brass and aluminium. - Stainless steel. - Plastic. - Maximum material thickness 4 mm. - For best durability, the use of a coolant/lubricant is recommended.

Electricians: drilling panels and boxes for cable gland installation. - Plumbing / HVAC: access holes for pipework and installations. - Metal fabricators: various sizes and enlarging holes. - Automotive: holes for cable installation (mobile phones, aerials, rerouting of electrical cables). - Maintenance technicians: various applications with different diameters and hole enlarging.

The main advantages over drilling with conventional drill bits are: with one step drill bit several sizes can be drilled - Better for enlarging existing holes. - More durable than twist drill bits. - More precise. - Cleaner holes. - Drilling in different types of plastic without cracking.

Milwaukee benefits

Surface dishing, drilling and deburring all in one motion.

Centring point for better centring, without the need to drill a pilot hole.

The geometry of the bit allows extremely precise drilling without leaving burrs and avoiding the skipping that could damage the material.

Optimised 2-flute geometry with a very sharp edge that makes it up to 2 times faster.

Custom-designed steel product with black obsidian coating for longer life, up to 4 times longer than conventional step drill bits.

Optimised for use at the high speeds of cordless tools.

Laser-engraved diameters for better visibility, even in the long term.

Removes burrs automatically.

Maximum shank grip in the chuck to ensure maximum torque transmission.

The kit includes:

Includes step drill bits 4 - 12 mm/1, 4 - 20 mm, 6 - 35 mm

PTFE coating: cool cutting, non-stick for faster cuts

Protects against corrosion and resin build-up.

Expansion slots: low vibration and greater precision

The slots are filled with polyurethane and act as dampers, isolating the teeth from vibration.

High-quality laser-cut steel: guaranteed precision.

Cobalt tungsten carbide teeth: sharp, clean cuts.

* Thin kerf: optimised for cordless tools, extra-thin cutting width to increase the number of cuts per charge.

* All types of wood: softwood / hardwood, plywood, laminated chipboard, melamine, MDF

** Identifies standard blades without PTFE coating and expansion slots.
