ANNULAR CUTTERS

HIGH SPEED STEEL

HSS annular cutters, with unique teeth geometry, provide clear cutting, fast feed rate, less vibration, smooth hole surface, and long tool life. They are better and quicker than twist drills. HSS annular cutters can be used on all kinds of magnetic drilling machines. They can be widely used in drilling steel, copper, aluminum, stainless steel, and plastic, in either plate or pipe form. The HSS annular cutters have gained huge popularity in the market. The entire range is available in various specifications that can be customized as per your requirements.

HSS (High Speed Steel) annular cutters are designed with a unique teeth geometry that allows for a cleaner and quicker cutting process. The two distinct types of teeth work together to deliver a fast feed rate with minimal vibration. This results in a smooth hole surface and extends the overall tool life, making these cutters an efficient and reliable choice for precise cutting tasks.
1.  Stage hardening. Combines maximum hardness at the teeth with superior strength at the cutter body, reducing breakage to a minimum.

2.  Inner ground cutting teeth. Helps stable "setting" of the cutter, reduces friction during drilling and helps slug ejection.

3.  Wall thickness matched to the diameter of the cutter, combining the best possible cutting time with strength.

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.  Precise pilot pin fitment for perfect centration, hassle-free pin retraction and controlled lubricant flow.
7.  Altering "continuous pre-cut" teeth geometry. Generates faster and more stable drilling performance and results in clear cuts of the highest precision and smooth, burrfree finishes.

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

9.  Specially designed blades for optimum stability and heatreduction.

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

11.  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.

HIGH SPEED STEEL - COBALT

Euroboor HSS-Cobalt annular cutters are made of Molybdenum-Chromium-Vanadium-Tungsten alloy High Speed Steel with an additional 5% Cobalt (HSS-M35), which results in higher hardness but minimizes the chance of cutter breakage. The HSS-Cobalt annular cutter is specifically designed to remain cool when cutting holes. All flutes are fully ground, resulting in super-fast feed rates and smooth holes in hard materials, providing better chip clearance and higher cutting performances. The M35 HSS-Cobalt annular cutter is widely used in the metalworking industry for its superior red hardness compared to more conventional high speed steels. This will lead to shorter cycle times in production environments due to higher cutting speeds.

Shank

Euroboor annular cutters are standard equipped with highprecision Weldon shanks. Depending on the cutter size and specification; 19.05 mm (3/4") or 31.75 mm (1 1/4").
