What is High Speed Steel Saw Blade

.

HSS Saw Blades are designed for cutting ferrous metal and plastic where maximum cutting life between sharpening is required. Ideal for sawing a wide variety of sizes and shapes such as extrusions, tubes, sheets, plates and some bar stock.

CIRCULAR SAWS IN HSS-DM05

Circular saws in high speed steel (5% molybdeunm content) suitable for cutting-off steels and alloys with hardness between 500N/mm and 800N/mm. The saw blades are used on manual semi-automaticand fully auto-matic sawing machine.

CIRCULAR SAWS IN HSS-CO5

Circular saws in super high speed steel (5% cobalt content) suitable for cutting off steels and alloys with hardness above 800N/mm The saw blades are used on semi-automatic and fully automatic sawing machine.

Surface Coating

VAPO

HV: 900 COF: 0.65 TEMP: 550℃ General Purposes
It produces a non PVD layer of iron oxide (Fe3O4) on the surface, which prevent it from rusting, reduce side friction and increases both the wear-resisting and the overall service life. Suitable for general cutting works.

TIN

HV: 2800 COF: 0.4 TEMP: 550℃ Steel Profiles
This is an excellent PVD coating for protecting HSS circular saw blade for wearing, which is a good choice for iron-based materials, and the cutting conditions require both abrasive and adhesive wear resistance.

TIALN

HV: 3500 COF: 0.5 TEMP: 800℃ Hard Steel
TiAlN is a new multi-layer wear protection PVD coating, suitable for strength materials>800N/mm2 and stainless steel, responds well to high speed and feed rates as well as extreme working conditions like dry cutting.

TICN

HV:3700 COF: 0.20 TEMP: 400℃ Stainless Steel
A high performance PVD coating suitable for severe abrasive wear cutting conditions. Recommended for high tensile strength materials and stainless steel, especially for high speed and feed rates.

Tooth Forms for Chosen

HSS blade tooth form

  • Tooth Form “A” & “AW”

    For thin metal slitting saw blade with a tooth pitch up to approx. 3.0mm. Advisable for brass. Tooth form “A” is suitable for slotting materials. All teeth of tooth form “AW” are beveled alternatively.

HSS saw blade tooth form

  • Tooth Form “B” & “BW”

    Suitable for cutting tubes and profiles made of steel or non-ferrous metals. Tooth form “B” is specialized in cutting very thin-walled pipes and profiles. All teeth of tooth form “BW” are beveled alternatively.

HSS teeth types

  • Tooth Form “HZ”

    This tooth is also known as form “C”. Teeth are ground according to the roughing and finishing tooth system. A tooth pair is consising of one roughing tooth (1/3 cutting width) and one finishing tooth (2×1/3 cutting width). According to the triple chip geometry the roughing  tooth is approx. 0.2~0.3mm higher compared with the finishing tooth. Tooth form “HZ” is suitable for cutting solid materials.
