DRY CUTTING


DRY CUTTING<br />

TYROLIT offers you the perfect product for every<br />

application!<br />

Long years of experience and enormous development expenditure have produced quality tools, which<br />

represent an unbeatable price/performance ratio.<br />

Innovative developments, such as the patented “HDS”-production process, combined with 100%<br />

inspection of the segment strength, guarantee safe and time-saving work with matured, well thought-out<br />

tools.<br />

The exclusive use of qualitative, high-quality raw materials and process stability, forms the basis for<br />

unsurpassed performances with regard to easy cutting ability and lifetime.<br />

Stability full utilization of the segments, safety and maximum reproducibility are results of TYROLIT quality<br />

thinking.<br />

The different product lines, Secur Extra, Secur, XPERT and Classic completely cover the requirements of<br />

the different target groups such as construction specialist shops, rental- and professional companies.<br />

• W = laser welded segments<br />

• S = angular segments as protection for the steel blade against<br />

“undercutting”<br />

• N = saw with hub for flush cuts<br />

• G = noise reduced steel blade<br />

<strong>Dry</strong> cutting


Application tips:<br />

• Before mounting the saw blade ensure that the machine cannot start (pull out main plug)<br />

• Rotational direction arrow of the saw blade has to match the spindle rotational direction<br />

• Not suitable for grinding – grinding can lead to serious injury through segment break outs<br />

• Saw specification has to be appropriate for the material to be cut<br />

• Do not tilt the saw blade in the cut<br />

• Do not carry out any curved cuts<br />

• Allow cooling down breaks, if saw blade is sparking heavily (use reciprocating cut)<br />

• Use protective clothing<br />

• Do not use too high pressure on the saw blade, weight of machine is sufficient<br />

Pressure to great saw cutting layer overheats<br />

Pressure to low saw cutting layer blunts, diamond grain polishes<br />

HDS-Technology “High Density Sintered”<br />

Patented production process<br />

Without HDS<br />

With HDS<br />

• Dense bond structure – high adhesion to steel core<br />

• Hardened steel core – no wobbeling with heating up – straight cuts<br />

• Large application spectrum – for all current construction materials<br />

A high heat arises especially with the cutting of metal.<br />

The new steel blade shape in connection with new raw<br />

materials brings a clear reduction of the temperature.<br />

Conical segments reduce the friction.<br />

(lower heat development)<br />

• No more overheated<br />

cutting layer<br />

• No more saws which<br />

do not cut<br />

• No more complaints<br />

Super thin saws – the noticeable difference:<br />

TYROLIT sets standards<br />

The ultimate of the dry cutting saws, the ONLY super thin diamond saw for concrete and building<br />

materials.<br />

Standard Super thin<br />

Maximum easy cutting ability with higher lifetime have made<br />

customers enthusiastic all over the world.<br />

Compromises are not tolerated:<br />

Stability, safety, universal application are absolutely necessary.<br />

Especially with thin saws, these characteristics are of decisive<br />

importance. The reduction of the layer width as well as the steel<br />

blade causes higher loading of the saw.<br />

The development of these saws was only possible through the<br />

special HDS-process.<br />

The result of the development work are saws with 1,2 mm width<br />

for Ø 115 and 125 mm, and 1,9 mm for Ø 180 and 230 mm.<br />

2,2 mm<br />

• Very short cutting-off times<br />

• Reduced machine load<br />

• <strong>Cutting</strong>-off without exertion<br />

• Cleaner cutting edges<br />

• Less material loss<br />

Noise reduced saws – The audible difference<br />

Noise is a subjective term for sound which is experienced as disturbing. Consequently<br />

noise is not a measurable, defined dimension, but as the noise of perceived sounds. The ear sense has no<br />

natural protection mechanism which prevents the noise having an effect on the ear. While for example eye<br />

pupils become narrower with strong incidence of light, the ear is permanently “switched on to receive”.<br />

As a result, noise is sound which disturbs, irritates, damages health, and can increase the accident danger.<br />

Noise reduced saws from TYROLIT reduce this noise pollution by up to 55 % and as a result make<br />

a considerable more pleasant working possible without loss of performance.<br />

This noise reduction is only possible through the sandwich steel blade developed by TYROLIT.<br />

A core with laser slots (Detenso) achieves a noise reduction of approx. 30%.<br />

EA+C – 2 in 1<br />

Up until now, it was impossible to machine two so different materials such as asphalt<br />

and concrete with only one tool, without noticeable loss of cutting characteristics.<br />

TYROLIT has the solution …<br />

SECUR EXTRA for asphalt and concrete (EA+C) allows the machining of these completely different<br />

materials with only one tool, while at the same convincing with easy cutting ability and lifetime.<br />

LONG LIFE – The lifelong difference<br />

Long life demands the highest quality of raw materials.<br />

The use of perfectly shaped diamonds and new bond materials enables highest lifetime values.<br />

New steel qualities of the steel blade guarantee maximum safety and stability up to the using up of the<br />

segments.<br />

Product advantages:<br />

• Reduction of set-up times<br />

• Lowering of tool costs<br />

• New bond system prevent premature diamond grain break out (“pull out”)<br />

• Laser welded segments<br />

<strong>Dry</strong> cutting


Remedying problems:<br />

<strong>Dry</strong> cutting blade loses cutting ability:<br />

Causes:<br />

• Specification not suitable for the cutting-off of the material involved<br />

• Saw blade running counter to the prescribed rotational direction<br />

• <strong>Cutting</strong> depth too great or application in deep cutting without reciprocal movement<br />

• No cooling down phases allowed by excessive sparking of the saw<br />

• <strong>Cutting</strong> pressure too high or too low<br />

• Machine drive power too low<br />

• <strong>Cutting</strong>-off materials such as steel, wood, aluminium<br />

Characteristics:<br />

• <strong>Cutting</strong> layer (segment) or steel blade shows blue discolouration<br />

• Diamond grain protrusion very low (finger nail test)<br />

• Bond thermally deformed (mushroom formation) or broken out<br />

Solution:<br />

• Select suitable application conditions and suitable saw type for application<br />

• Sharpen cutting layer before further use through cuts in a sharpening plate or in abrasive material such<br />

as for example sandstone<br />

<strong>Dry</strong> cutting saw blade gets cracks:<br />

Causes:<br />

• Saw blade used for lateral grinding (not allowed!!)<br />

• Application in curve cutting<br />

• Saw blade jamming in the cut<br />

• Extremely high cutting pressure<br />

• Saw blade not designed for the application in hand<br />

Characteristics:<br />

• (Hairline) cracks going out from the slot base<br />

Solution:<br />

• Select suitable application conditions and suitable saw type for application<br />

<strong>Dry</strong> cutting saw blade – breaking off of layer parts:<br />

“Undercutting”<br />

Segment<br />

Causes:<br />

• Application in curve cut<br />

• Saw blade jamming in the cut<br />

• <strong>Cutting</strong> in “loose” or very abrasive material<br />

Wear<br />

Steel core<br />

Characteristics:<br />

• Layer parts missing and hairline cracks in the segment<br />

• Undercutting effect in transition area, segment / steel blade<br />

Solution:<br />

• On no account use the saw blade further!<br />

• Use of protective segments with abrasive materials to<br />

avoid the undercutting effect<br />
