Diamond blades are sharpened by cutting abrasive materials, e.g. silicate brick or aerated concrete blocks. This process exposes new diamond grains and restores cutting performance.

The choice of diamond blade depends on the material being worked and the tool's diameter. Different models are used for concrete, and others for tiles or porcelain stoneware. Choose a diamond blade from the catalog.

A diamond cup wheel works best for grinding concrete. It quickly removes unevenness and delivers high work efficiency.

A diamond blade cuts concrete, stone, ceramics, porcelain stoneware and asphalt. Thanks to its diamond segments, it copes with very hard materials.

For tiles, a continuous-rim blade is best, as it gives smooth edges. Segmented blades can cause chipping.

For porcelain stoneware, turbo or continuous diamond blades are recommended. They provide precise cutting without cracking.

A diamond blade is worn out when it stops cutting effectively or its segments are heavily worn down. Visible overheating is also a sign of wear.

For glazed tile, thin continuous blades work best. They minimise the risk of cracks and chipping.

A 125 mm diamond blade should be matched to the material and the grinder's power. This is the most popular size for both home and professional work.

For concrete, it's best to choose a segmented blade with high durability. It provides fast, efficient cutting.

For wet cutting, water-cooled diamond blades work best - continuous blades for ceramics/glazed tile, turbo blades for porcelain stoneware, and segmented blades for concrete/stone. Choose models with high-quality embedded diamonds designed for wet cutting.

The price of a diamond blade depends on its diameter, quality and manufacturer. It usually ranges from a modest amount to several hundred PLN. You can check current prices at https://distar.tools/catalog/diamond-blades

Popular brands for cutting metal include: DISTAR (high-quality professional blades with strong wear resistance), Baumesser, and Makita. These manufacturers offer cutting blades of various thicknesses for both home and professional tasks. Choose a blade that matches your tool's diameter and the type of metal, to ensure maximum safety and efficiency.

For cutting metal, a thin metal cutting blade 1-1.5 mm thick is used. It provides precise cutting and minimal material loss. It's important to match the blade to the angle grinder's diameter and to the type of metal.

The best blade for cutting metal is one that combines high cutting speed, durability and safe operation on an angle grinder.

For a drill, it's worth having a set of drill bits for different materials, a keyless chuck, an SDS adapter and a guide for drilling perpendicular holes. The choice of accessories depends on the type of work being done.

An SDS adapter fits drills with a matching spindle chuck, most often threaded or keyless. Check compatibility with your specific model before buying.

For a bench drill, it's worth choosing a vice, reduction sleeves and a set of twist drill bits in various diameters. Stable clamping of the workpiece increases drilling precision and safety.

The most popular are bit sets, magnetic holders, extensions and angle adapters. They let you work in hard-to-reach places and match the tool to different types of screws.

Most bits have a standard 1/4-inch (6.35 mm) shank that fits popular screwdrivers. However, it's worth choosing the right tip type and size for the type of screw, to avoid damaging it.

An angle adapter lets you drive and remove screws in tight, hard-to-reach places where a standard screwdriver won't fit, e.g. near furniture or in corners.

The Mechanic Slider 45 is an attachment for an angle grinder that allows precise cutting of tiles and glazed tile at a 45-degree angle, making it easier to create neat corners with no visible edges.

The Mechanic Slider 45 attachment fits popular 115/125 mm angle grinders with a suitable mount. Check compatibility with your specific model before buying.

Thin diamond blades for tiles and porcelain stoneware, 115-125 mm in diameter, work best with the attachment, giving a clean cut without chipping when cutting at an angle.

The Mechanic Slider 45 Pro version usually has a sturdier build, more precise angle adjustment and greater durability under intensive use, making it better suited to professional work.

Yes, the Pro version is designed for frequent, intensive use on building sites, giving greater cutting precision at a 45-degree angle and a longer mechanism service life.

The attachment is mounted on the angle grinder's spindle in place of the standard guard, following the manufacturer's instructions, and then the appropriate cutting blade is installed.

The Drillstream dust extractor is mounted on a drill or drill rig and channels the dust produced during drilling straight into a construction vacuum cleaner, reducing dust at the work area.

The Drillstream dust-extraction adapter is designed to fit common diamond core bit diameters, though it's worth checking compatibility with your specific core bit model before buying.

The aluminium version of the Drillstream dust extractor has a sturdy, lightweight construction resistant to mechanical damage, giving it a longer service life on the building site.

The Drillstream extractor connects to a standard industrial or construction vacuum cleaner using a hose of typical diameter, allowing effective dust extraction right at the drilling spot.
