TUNGSTEN CARBIDE TIPPED

Euroboor TCT (SANDVIK) annular cutters are equipped with a spiral flute which creates optimum chip removal and makes seizure virtually impossible. These annular cutters are used for example in hardened materials such as HARDOX steel, stainless steels and high tensile strength steel such as railway tracks. Because of the above composition, and when used in a proper way, these cutters are less susceptible to breakage than standard High Speed Steel cutters, especially in larger diameters and lengths.

Extremely hard and durable tungsten carbide cutting teeth (SANDVIK) for the hardest of drilling tasks. Offset positioning for the lowest possible heat development.
1. Extremely hard and durable tungsten carbide cutting teeth (SANDVIK) for the hardest of drilling tasks. Offset positioning for the lowest possible heat development.

2. Optimised cutting angles for shortest drilling times and clearest cuts.

3. Special alloy body for optimum strength and durability.

4. Tapered inside fitment prevents the cutter getting stuck. Guaranteed slug ejection with usage of the correct pilot pin.

5. Precise shank fitment for maximum interchangeability and close tolerance drilling without run-out.
6. Altering "continuous pre-cut" teeth geometry. Generates faster and more stable drilling performance and results in clear cuts of the highest precision and smooth, burr-free finishes. SANDVIK carbide tipped.

7. Well-thought-out spiral flute angles for optimal chip removal.

8. Specially designed blades for optimum stability and heatreduction.

9. Number of flutes and teeth matched to the diameter of the cutter for the best tooth load and superior cutting speeds.

10. Precision ground shanks for optimum fitment of the cutter itself in the tool holder and of pilot pin in the annular cutter. Increases safety, stability and accurate hole dimensions.

Shank

Cutters with a diameter up to 60 mm (for Depths of Cut like 35, 55, 75, 100, 150, and 200 mm):
   - These use a 19.05 mm Welnit shank.

Cutters with a diameter of 61 mm and up (regardless of Depth of Cut):
   - These use a 31.75 mm Weldon shank.

So, in short:
- Smaller diameter (up to 60 mm) = 19.05 mm Welnit shank.
- Larger diameter (61 mm and up) = 31.75 mm Weldon shank.
