Description

Product Description of the Wide Belt Calculator - Mirka Hiolit XO Heavy-Duty Cloth Wide Belts

Hiolit XO is a semi-open stiff universal abrasive for belt sanding and other machine sanding where it has excellent edge wear resistance and durability. In particular, it produces high quality results on challenging materials – for example, grits 36–80 are suitable for aggressive sanding, such as severe rust damage, as well as other sanding operations where large amounts of material need to be removed.

Technical Specifications
• Grain: Blue fired aluminium oxide
• Color: Maroon
• Backing: Polyester cloth P36-P80, X-weight cotton/cloth P100+
• Bonding: Resin over resin
• Grit range: P36-P240
• Coating: Semi-open

Applications & Materials
• Heavy duty aluminium oxide belt optimised for metal and wood sanding
• Designed for use on hard woods and soft, resinous woods such as pine due to reduced clogging from semi-open coat modern coating technology
• Long service life with even finish throughout
• Strong polyester cloth or cotton-cloth backing (dependent on grit size) with very high stability and rigidity
• More economical than equivalent paper materials; cloth backing often provides at least twice the life of paper

Why Use Aluminium Oxide?

Mirka Hiolit XO Heavy-Duty Cloth Wide Belts have an aluminium oxide grit, which is considered to be a good all-round or general purpose grain that works well on various applications.

In disc form (i.e. velcro-backed, fibre or flap discs) it is best suited to metalworking, such as aluminium and carbon/mild or stainless steel, and leaves a finer scratch pattern than other more aggressive products such as zirconia. This, in combination with its wide range of grades (generally between P36 - P400) means that it is often used prior to beginning some form of polishing process. There are also some benefits in woodworking, for example fibre discs are quite common in the floor sanding industry for the initial stages, with heavy stock removal requiring coarser grits.

Aluminium oxide is also quite common with abrasive belts, and can have specific features to improve performance on particular substrates. For example - when working on soft woods/metals it can often begin to transfer to the belt and quickly cause it to "clog" or dull, and so a more suitable material to use would be one with either a semi-open or open coat. With these there is less abrasive on the belt which leaves more space between the grains, the idea being that the loading would occur here rather than on the grit itself (the other effect of this is however that due to less abrasive being present the belt is in turn less aggressive.) In reverse a closed coat means that 100% of the surface of the belt is covered with the grain, so will take off more stock but is recommended only for hard woods and metals that are not prone to clogging. Aluminium oxide belts have either a paper or more durable cloth/polyester backing, with paper primarily being either a narrow or wide belt and most popular in woodworking, while cloth/polyester are more prominent in metalworking and available in a greater variety of sizes, again including narrow and wide but also file belts and portable sander belts.
