Karnasch premium HSS-XE / powder steel annular cutters

Best cutting performances of our annular cutters due to HSS-XE special steel and ASP powder steel

Karnasch Professional Tools annular cutters of high alloy HSS-XE special steel combine innovative step hardening and optimized cutting edge geometries for the best possible combination of tool life and cutting performance.

Very few manufacturers are able to fabricate step-hardened annular cutters – this enables us to achieve the maximum hardness of 68 HRC at the tooth tips and a flexible annular cutter. The patented Durablue coating increases the tool life even further due to the extremely improved surface hardness, even at high temperatures in use without cooling. Karnasch HSS-XE annular cutters are available in cutting depths of 30 mm, 55 mm, 80 mm and 110 mm, in diameters from 12 mm to 60 mm.

For materials that are extremely difficult to machine, such as hardox, titanium, inconel and rail steel, we recommend the use of the highly wear-resistant ASP powder steel annular cutter. It is specially made of ASP powder steel and guarantees maximum tool life. Karnasch powder steel annular cutters are available in cutting depths of 30 mm and 55 mm, in diameters from 12 mm to 36 mm.

HSS-XE annular cutters with innovative step hardening and optimized cutting edge geometries

The Karnasch HSS-XE annular cutters are available in three versions: BLUE-LINE, GOLD-LINE and SILVER-LINE.

The BLUE-LINE annular cutter is the most frequently used Karnasch annular cutter which is ideally suited for all steels up to 1100 N as well as stainless steels.

The GOLD-LINE annular cutter is the most frequently used uncoated HSS-XE annular cutter. Due to its special GOLD-TECH surface treatment with full grinding, it is excellently suited for drilling in steel up to 900 N as well as in stainless steel.

The SILVER-LINE annular cutter, on the other hand, is an excellent universal drill. With its step hardening and 7 blade geometry, it is ideally suited for drilling of all structural steels up to 750 N.

KARNASCH INTERNAL COOLING

Drills with internal cooling for optimal cooling and lubrication

Maximum resilience for challenging applications.

Karnasch internal cooling guarantees optimal cooling results and presents obvious advantages as compared to external cooling. On the one hand, the cooling of the cutting edge can individually be optimized, with the result that the heat development is considerably reduced. The special power chamber by Karnasch ensures an increased coolant leak - at the same pressure but also at low pressure. On the other hand, Karnasch internal cooling removes the chips more efficiently and improves the overall cutting performance significantly. In addition to higher productivity, Karnasch internal cooling enhances tool lives and prevents premature tool breaking, which in turn leads to considerable cost savings.

Advantages of the Karnasch cooling channel drills

  • Optimal tool life even under highest loads (optimal cooling and lubricating effect)
  • Increased drilling speed
  • Chips are more easily removed from the drilling range
