DRILLS

Versatile Drills made of High-Speed Steel.

Drills made of High-Speed Steel (so called HSS drills), are manufactured of highest quality materials from carefully selected steel grades. High-speed steel refers to high alloyed tool steel. Compared to ordinary tool steel, up to four times higher cutting speeds are possible when using HSS drills.

FEATURES

SPIRAL SHAPES. In general HSS drills are characterized by its spiral shape.

| N-Type – Normal-Spiral.
Machining of materials of normal strength and hardness. Suitable for structural steel, cast irons, etc. Typical metal drills.

| H-Type – Lang-drawn Spiral.
Machining of materials of high strength and high hardness. Suitable for short-chipping materials such as tempered steel.

| W-Type – Short Spiral.
Machining of materials of low strength and low hardness. Suitable for long-chipping, soft materials such as aluminium, copper, etc.

ALLOYS. HSS-drills can be optimized by alloying them. Alloying tools is an appropriate measure for increasing their cutting performance, it offers a better chip removal and makes the tool more wear-resistant.

Chromium components as well als cobalt improve hardness and heat-resistance of the drills.

| HSS-Co Drills.
For particularly tough and hard materials (corrosion-resisting steel). Cobalt content of up to 16%.

| HSS-E Drills.
For materials of high strength, such as stainless steel. Cobalt content of up to 8% (M2).

| HSS TiN-Drills.
Titanium-nitride-coated drills are particularly suitable for cutting steel and non-ferrous metals.

| HSS-PM Drills.
High-speed steel (HSS) manufactured drills that are using powder metallurgical techniques, contain a higher part of alloy elements. Steel manufacturers are continiously developing new PM steel grades (e.g. PM HSS-E) to increase cutting capacity.

BENEFITS

Even at higher temperatures (up to approx. 600° C), high-speed steel keeps its hardness. That’s why HSS drills are considered as extremely durable and resistant. HSS-drills are very popular in small- and medium batch production. The HSS drills supply good quality at a reasonable price. Also under instable machining conditions HSS drills are to be preferred.
