COMPATIBILITY AND APPLICATION

• ✴️ The mandrels have standard dimensions and fit most Dremel-type mini grinders and other rotary tools that accept mandrels with the specified diameters.

• The self-expanding rubber cushion in the spindle ensures good belt hold and an even finish.

• If the belt comes loose, stop the machine and check the mounting.

⚙️ 3 SIMPLE STEPS

• 1- Loosen the screw in the spindle (arbor).

• 2- Place the sanding belt on the drum so that it fits without any play.

• 3 - Tighten the screw, run the tool briefly at low speed and check for proper contact.

• ✅ Three sizes of collets - full versatility: 1/2", 3/8" and 1/4" strips and the corresponding mandrels (spindles) fit most mini grinders (e.g. Dremel) - you work without worrying about compatibility.

• ✅ Corundum - efficiency and durability: aluminum oxide grain works Aggressive and lasts longer, so you get the job done faster and change cartridges less often.

• ✅ Self-expanding spindles with rubber cushion: The spindle holds the belt securely, ensuring a consistent, vibration-free finish – better control and fewer rework.

• ✅ Simple 3-step assembly – quick belt changes: loosen, tighten, tighten – minimal downtime during replacement, so work runs smoothly.

• ✅ Lower operating costs: large number of belts and durable abrasive material means less frequent repurchase of materials and lower operating expenses.

• ✅ Precision in detail: Small sleeve sizes allow you to reach narrow and curved places - better detail finishing, less hand sanding.

⚡ ELECTRONICAL ALUMINUM OXIDE - THE POWER OF ALUMINUM OXIDE

• The grain of this abrasive strip is made of electrocorundum, material that guarantees exceptional wear resistance and excellent sanding efficiency.

• Aluminum oxide is an ingredient found in the best products. Why?

• Because it provides a strong, aggressive abrasiveness that allows you to complete any job faster and more precisely.

• High durability means you don't have to constantly replace the sanding sleeve, which saves you time and money.

⚡ GRIT AND DURABILITY

• All belts in the set have 120 grit - this is a universal grit that provides a good balance between material removal and a smooth finish.

• Durability depends on the material and intensity of use.

• For light work, you will be satisfied with the long service life. use.

• When working with metal or aggressively sanding, wear will be faster.

⭐ MATERIALS - WHAT YOU CAN USE THIS SET FOR

• Below you will find practical tips on what to sand with these strips and how to do it safely and effectively.

✅ Wood (soft and hard)

• Excellent for smoothing edges, modeling details and removing excess material.

• Recommended speed: medium–high (depending on the tool and arbor size).

• Note: with hardwood,monitor the temperature – too high a speed can burn the surface.

✅ Metal (light machining, aluminum, copper, soft alloys, minor steel touch-ups)

• Suitable for finishing, deburring, and polishing details, but not for heavy machining of hardened steel.

• Recommended speed: lower–medium; use short, intermittent movements, relieve the tool, and check belt wear frequently.

• Belts wear faster when sanding metal for extended periods – keep this in mind.

✅ Plastic and resins (epoxy, ABS, polyethylene, modeling resins)

• Excellent for shaping details and smoothing edges.

• Recommended speed: low-medium to avoid overheating and melting the material.

• Working with resins can generate fine chips - use a mask.

• Good for stripping old varnish and preparing for a new coating.

✅ PCBs, thin metal components and electronic details (very carefully)

• Possible for delicate work at low speeds, but not recommended for electrically sensitive components; Fine filings conduct electricity - protect components and clean the surface after use.

• ☝️ Rapid wear - natural with hard materials; a large number of belts minimizes operating costs.

• ☝️ Belts unravel - usually a matter of assembly or too high RPM; Correctly tightening the arbor and using the appropriate number of turns for the material being processed eliminates the problem.

• ☝️ Doesn't fit my tool - check if your tool accepts 1/2", 3/8" or 1/4" arbors; if so, the set will work.

• ☝️ Always wear safety glasses and gloves.

• ☝️ When working for longer periods, use a dust mask or extraction.

• ☝️ When working with metal, work at lower speed and check the condition of the belt regularly.

• ☝️ Do not use on glass and ceramics.
