Company GSP – High Tech Saws, s.r.o., resident in Zborovice, is the traditional cutting tools producer. Beginnings of the manufacture date back to year 1948 when company Pilana established here its branch plant that has produced metal cutting circular saw blades from the very beginning.

The produced tools were during the years delivered with the brand PILANA (until 1992), later SCHULER PILANA (until 1999), and are known as brand GSP – High Tech Saws now.

With the logo change corresponds also the change of our strategy towards our clients. Company GSP – High Tech Saws turns from a mass supplier of standard tools to a supplier who produces specialized tools according to the demands of the market and of the end user; also in small quantities.

We believe that you as our client will benefit from our company mission of non-standard tools production. We are looking forward to our cooperation.

The product range consists of: CUT OFF high speed steel blades from Dmo5 , HSS Co5%, HM   TiN, TiCN, TiAlN surface modification of HSS circular saws, repairing and grinding Rotary knives for cutting rubber, leather, paper, isolation materials and plastics, cutting thin walled tubes, hoses, but also non-ferrous metals and steel TCT circular saws and cermet tipped saws Cermet tipped saws "Throw away" Hot and friction saw blades for metal cutting circular saws (machines)

The method of continously investing in new and advanced production processes, closely controlled by sound technical and commercial management expertise has brought GSP - High Tech Saws, s.r.o. to the forefront in the manufacture and sale of sawblades. GSP - High Tech Saws, s.r.o. is the only firm mass producing HSS metal cutting sawblades in the Czech Republic.

CUT OFF High Speed Steel Blades from HSS/Dmo5 and HSS/Emo5

Company GSP- High Tech saws s.r.o. produces HSS metal circular sawblades in diameters varying up to 720 mm in various designs. The tooth forms most used are HZ, BW, B, AW, A, VP and 'Chipbreaker' . Production is based on DIN standards 1836, 1837, 1838 and 1840, extended by the refined company GSP manufacturing standards. The delivery program consists of a range of standard sawblades which can be delivered from stock and a range of special sawblades to be produced to customer specifications. The HSS sawblades are supplied as standard in high speed steel grade M2 = DIN 1.3343, but can also be delivered in cobalt-alloyed steel grades, such as M35 = DIN 1.3243 and S390 Powder Metallurgy Steel. These blades are specifically suited for use in manual, semi-automatic and fully-automatic sawing operations. All blades are hardened to 64/65 RC, triple tempered and press quenched. This manufacturing method produces the flattest and straightest saw blade in the world today. The HSS sawblades can be supplied in among other things bright, steam-treated, flash-chrome, titanium nitride, titanium aluminium nitride, titanium carbon nitride or chrome nitride coated design.

Hot and Friction Saw Blades for Metal Cutting

Hot and Friction Saw Blades up to 2500 mm diameter are tools of high efficiency made from well proven steel plates with a tensile strenght of 850 bis 950 N/mm2. Friction saw blades are used for cutting of steel tubes and profiles by low working temperature, it means by material temperature up to 250°C. They are made from chrom-vanadium steel marked (DIN 1.2235) and they are heat-treated to reach the optimum ratio of tenacity and hardness, which is suitable for cutting of material with high circumferential cutting speed. The cutting principal consists in melting of material in cut place caused by special kind of teeth. GSP - High Tech Saws, s.r.o. can manufacture these tools with taper of hollow ground. Choice of flange diameter, number of teeth, central bore diameter, thickness, driving holes number and diameter is possible. Hot and friction saw blades are used for cutting slabs - square billets - plates - tubes – profiles. Hot saw blades are used to cut metals with a temperature in excess of 850° C. When sawing metals below a temperature of 250° C, friction saw blades are used. Both sawing methods are a friction cutting. The friction heat in the cutting gap ae produces temperatures which bring the material in a soft, almost plastic condition. In order to clear debris from the tooth gullet a copiuos or heavy flow of coolant (preferably under high pressure)
is essential for efficient cutting . The required cutting speed is Vc=100-140 m/sec. Depending on the material to be cut the feed reached is Vf=80-2000 mm/min. The tooth geometry and tooth pitch are determined by the section and quality (analysis) of the material to be cut and the sawing machine. Heat treatment of the saw blades of 1200-1250 N/mm² (up to 1000 mm diameter) or hardening of the teeth up to Rockwell C 58 (up to 2500 diameter) gives an increase in both blade life and in number of cuts between resharpening.

HSS circular knives

In the product range of GSP - High Tech Saws, s.r.o. company there are also high-efficient cutting tools manufactured on request which are generally known as circular knives. Circular knives in HSS-DMo5, HSS-Co 5%, K110, K190 PM and S 390 PM Steels are used not only for cutting rubber, leather, paper, isolation materials and plastics, cutting thin walled tubes, hoses, but also non-ferrous metals and steel. Cutting edges of these tools are various according to the kind of cut material. Applications are on semi and fully automatic machines. Our range spans from ø 20 mm through to ø 600 mm and the standard execution of all circular knives is HP-GRIND finish but readily available in our P.V.D. (Physical Vapour Deposition) coatings too. Company GSP manufactures also the highest quality food and meet processing rotary knives in the industry from 3" to 20" in diameter.  We manufacture with the latest CNC grinding equipment to achieve up to 3 times longer blade life than those manufactured using files. We currently have a manufacturing capacity of 1" diameter thru 72" diameter, in various thicknesses.

Segmental saws

The segmental circular sawblades consist of a CrV steel disc on to which hardened toothed segments are mounted and secured by rivets. This principle makes it possible to repair a segmental sawblade after tooth or segment breakage by simple replacing one or more segments. Our current capacity range for segmental saw blades is 10" diameter thru 120" diameter. Within this range we produce special diameters and thicknesses that offer our customers the widest spectrum of products. The most commonly used tooth forms are HZ and BW. They are produced and controlled to the GSP manufacturing standards whereby precise sizing and close tolerances are guaranteed. The segmental sawblades are supplied as standard in high speed steel grade M2 = DIN 1.3343, but can also be supplied in cobalt-alloyed steel, such as M35 = DIN 1.3243 and M42 = DIN 1.3247.The segmental sawblades can be delivered in bright, titanium nitride, titanium carbon nitride, titanium aluminium nitride or chrome nitride coated design.

TCT circular saws and cermet tipped saws

The tungsten carbide tipped sawblade (TCT) consists of a CrV steel disc to which carbide tips are brazed. Company GSP produces TCT sawblades in diameters from 150 to 2000 mm in various designs. The TCT sawblades are produced and controlled to the strick GSP manufacturing standards. The delivery program consists of 2 main groups, one range of TCT for ferrous and non-ferrous materials. The standard program can be supplied from stock, while special sawblades are produced to customer specifications.

Alpha Cutter

The cut-off knives for cutting profiles and tubes from carbon, low-alloyed and stainless steels. The cutting effect is achieved with combination of high pressure and high speed. Burrfree cut of highest precision is achieved and the cut profile is free of deformation. Very short cutting times enable using these tools not only in stationary machines, but also in production lines during continuous cutting.
In standard modification Alpha Cutters are made with PVD coating to prolong their lifetime, decrease friction coefficient and to avoid cool surfacing. These tools aren´t standardized at all, that´s why they are always tailored. For making the offer sending the drawing
or sample is enough.
