WiN - woodworking INTERNATIONAL is the international magazine for the woodworking industry. We report on all aspects of woodworking from board materials, wood treatment to machines, tools and technical know-how, from timber engineering supplies to the latest developments in technologies and markets.

TOOLS High degree of

TOOLS High degree of precision, deep cuts New 18 volt cordless plunge cut circular saw ”We are aware of the high requirements of our customers - especially when it comes to plunge cut circular saws, the top tier among circular saws. Therefore we have developed an innovative and powerful saw that meets the high requirements for precision and cleanliness, And it can do even more”, says Daniel Grün, Manager Product Management Wood & Compressed Air at Metabo. The new 18 volt cordless plunge cut circular saw KT 18 LTX 66 BL supplements the extensive range of saws of the Nürtingen power tool manufacturer. It is the only cordless plunge cut circular saw on the market with a cutting depth of up to 66 millimetres - and this with the same size like standard 55 millimetre plunge-cut saws.The KT 18 LTX 66 BL is equipped with a Brushless motor of the latest generation, allowing it to make powerful plunge cuts into the material. ”The motor and the double reduction high-performance gear make the saw particularly powerful and durable. At the same time, it is compact and requires only one battery pack. With one 8.0 LiHD battery pack it can go through more than 100 metres of 19 millimetre chipboard”. For precise and clean working: The 18 volt plunge cut circular saw KT 18 LTX 66 BL sits without clearance on the guide rail. The supplied dust collection bag collects falling chips.

The new 18 volt cordless plunge cut circular saw is ideal for professionals in the building trade and renovation, such as carpenters, floorers and drywall constructors. However, it is also very well suited for booth builders and shopfitters. The variable speed of the KT 18 LTX 66 BL can be quickly set via a thumbwheel. Like this it can be used for different materials. The newly designed accessory programme from Metabo offers a large selection of saw blades with 165 millimetre diameter. The user can find the position for the saw blade change directly at the scale for the cutting depth. The saw blade can be locked here automatically and thus changed quickly and easily. Precision work ”For all materials applies: The KT 18 LTX 66 BL saws in an absolutely precise and clean manner”, says Grün. The fit on the guide rail can be adjusted without clearance. They are compatible with the ”FS” guide rail system from Metabo and many other standard rail systems on the market. Even with guide rail, the plunge cut circular saw saws up to 60 millimetre thick workpieces. Users can adjust the cutting depth down to the millimetre on the large scale. Since it has a double indicator, the cutting depth with and without guide rail can be read. The angle setting has stops at 0 and 45 degrees. The swivel range can be extended to -1 and +46 degrees for customised transitions between workpiece edges. Keeping the ground free from chips ”We have attached great importance not only to absolute precision, but also the topic of cleanliness when developing the saw”, says Grün. ”Pieces of material flying about are annoying, especially when working indoors or when sawing gypsum fibre or cement-bound boards with their fine dust.” The supplied dust collection bag already accommodates a major part of the chips. A vacuum cleaner can also be connected for maximum cleanliness, such as the new Metabo cordless vacuum cleaner ASR 36-18 BL 25 M SC. Thanks to the CordlessControl system it switches on automatically as soon as the saw is in operation. Manual switching on and off is not required. If you would like to work without extraction, the sawdust ejection nozzle can be rotated and locked individually. www.metabo.de 14 No. 4 • October 2020

TOOLS Team work for an even more precise sizing Clean milling results thanks to efficient chip caption The main advantage of the DIAMAY AirStream is the high chip caption rate of 99 percent which can be reached thanks to the patented AirStream design jointly developed by a LEUCO and HOLZ- HER. The chips are guided through bores in the gullets into the extraction hood of the machine. The geometries of tool and extraction hood are exactly adapted to each other. That’s why machine and tool work perfectly together. Due to the introduction of the precise tool adapter HSK 32R, LEUCO and HOLZ-HER achieve a higher quality during jointing on edge banding machines. For these machines, the enhanced jointing cutter LEUCO DIAMAX AirStream with HSK 32R clamping is now available. This combination guarantee highprecision sizing with standard machines for trade and industry. The new cutter is used for the first time on HOLZ-HER machines. The latest result of the cooperation between LEUCO and HOLZ-HER is the introduction of the HSK 32R clamping for edge banding machines. Thanks to a combined traction and locking function, these compact tool adapters ensure a concentric accuracy of 20 microns. The conventional clamping by means of a double keyway presents a concentricity deviation of up to 60 microns. HOLZ-HER is the first machine manufacturer who offers jointing cutters with a high-precision tool adapter for compact machine series. LEUCO succeeded in adapting the big jointing cutter to the slim interface of the size HSK 32R. For this reason, this cost-effective technology is available for the first time for machines usually used in the trade sector. A multiple hogging is almost completely avoided by the high chip caption rate which results in a higher edge life of the cutter. In addition, the machine remains clean for a much longer time. This means less machine downtimes and cleaning work. Especially for edge banding machines, it is very important that there are no chips on the cutting edges. Before glueing, the edges must be completely even and clean. Another advantage of the DIAMAX AirStream is the smoother running which reduces the noise level by two to three dB compared to other cutters. For this, LEUCO has optimized the flow behavior of the jointing cutter by changing details such as the cutting edges and the gullets. The bundling of the air flow in front of the extraction hood by the AirStream design has an additional noise-reducing effect. Due to the combination of these two innovative developments, a new standard for precise, clean and silent jointing is set. www.leuco.com LACH DIAMANT expands sharpening and grinding service For diamond-wood, -plastic tools and for cutting tools for aluminium As of now, LACH DIAMANT, well-known pioneer in the field of diamond tools, offers its expanded machine sharpening capacities for the sharpening service of diamond tools for the furniture- and composite-industry as well as for the automotive industry.
