User questions & answers

Question: Need replacement wheel or arm assm. Who sells them
Answer: Yes, the FlexVolt batteries will work with our 20V and 60V product line.
Question: Powerful .65 horsepower motor?????? what motor? it's air powered... what does this mean? i though it was corded
Answer: Sadly no, so close to perfect as usual. why can't I run items like this or my 60volt compressor when power is available? I have the 20 v fan and that has a cord option so it can be done. Metabo is now offering a converter pack that works on all their tools, maybe dewalt will take the hint.... This would be a perfect light if there was a cord socket, then when power gets tripped or isnt available the battery kicks in. Come on dewalt give us the flex volt power 120 adaptor!!!!!!!!!!!!!!
Question: Is the front wheel made from steel or rubber
Answer: The hole saw has a 3/8 shank and is less than three inches. The mandrel that you would use is DW1805
Question: is this battery powered
Answer: Yes, it will cut through metal

Make Light Work of Tough Tasks with Cubitron II

Ideal for tough detail work like cleaning, deburring, blending and finishing as well as working in small confined spaces. 3M Cubitron II File Belt 786F is available in three grades – 36+, 60+ and 80+ – and widths including 3/8”, 1/2” and 3/4” as well as lengths of 13”, 18” and 20.5”.

The exceptionally fast cut and long life of 3M ceramic abrasive grain enable this slim belt to accomplish a remarkable degree of work. Its fast cutting action helps eliminate burning or other forms of thermal damage, as well.

About 3M Cubitron II and Precision-Shaped Grain

3M Cubitron II abrasive discs, cutoff wheels and file belts have raised the bar for high-performing abrasives. Cubitron abrasives feature Precision-Shaped Grain (PSG) technology, which allows 3M engineers to control the geometry of the abrasive grain for a truly fast, efficient cut. Instead of simply crushing the abrasive into particles, 3M uses microreplication to uniformly size ceramic grains and precisely shape them into triangular structures – essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. What’s more, PSG fractures during use to maintain sharp abrasive edges. The result: Cubitron II cuts 30% faster and lasts 2x longer than conventional ceramic abrasives.

An Alternative to Spot Weld Drilling

The 3M File Belt Sander and 3M Cubitron II File Belt 786F are a great addition to body shop tool rooms. They are a vastly superior alternative to spot weld drilling.

In addition a traditional spot weld drill goes back on the shelf. The versatile file belt tool can also be used for other jobs.

Product description

3M Green Corps Sanding Abrasive File Belt removes spot weld and hem flanges as well as grinds in tight areas for fast and efficient removal of paint, corrosion and rust. Aluminum oxide abrasive delivers a fast cut and long life.

From the Manufacturer

3M Green Corps Sanding Abrasive File Belt strips away paint, rust and welds in hard-to-reach locations on automotive bodies. Aluminum oxide abrasives work quickly in stripping away paint down to bare metal, plastic or fiberglass, giving automotive paint technicians a clean surface for restoration work. This automotive paint stripping belt works with 3M File Belt Sander 28366 and other belt tools.

These file belts can quickly remove stock in tight areas while allowing technicians increased control over other methods of structural disassembly. A grinding aid allows for cooler grinding, which reduces heat on the surface of metal substrates to preserve structural integrity.

Aluminum oxide is a popular abrasive among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives quickly wear down with use. Due to its fast cut-rate, hardness, strength, and low heat retention, it is widely used in grinding applications. The abrasive has been resin bonded for heat resistance.

  • Aluminum oxide minerals deliver a fast cut rate

User questions & answers

Question: is the price quoted $32.90 for 20 belts
Answer: Wasn’t aware of issue with legs; works as intended.
Question: Whats the quanity of Belts included
Answer: I find that as a general rule of thumb, Leds use about 10 watts per hour per 1,000 lumens. So this light, on high, puts out 3,000 lumens which should be somewhere around 30 watts per hour. So a 5ah 18v/20v battery has about 90-100 watt hours of energy in it, so you can expect about 3 hours of runtime on high. A 9ah should get almost 6 hours and a 12ah almost 8.

Question: What size air tank is required/recommended to run this sander
Answer: This is a great tool for a vast variety of jobs. very powerful, but you at not going to run this tool very long on a small pancake type compressor. a minimum requirement would be a least 3 hp with 40 gal tank for regular home owner use. 5 hp two stage would be better. if you don't have the air this tool will not perform as intended.

3M Cubitron II File Belt 786F

3M Cubitron II File Belt 786F is a 3M best-in-class abrasive belt, designed for use with the 3M File Belt Sander, for tasks like grinding out rivets and removing spot welds. 3M Precision Shaped Grain is resin-bonded on a heavy duty backing for a more consistent finish, cooler operation and two times more belt life. The resin bond and a grinding aid keep this belt cutting cool and sharp.

Make Light Work of Tough Tasks with Cubitron II

Ideal for tough detail work like cleaning, deburring, blending and finishing as well as working in small confined spaces. 3M Cubitron II File Belt 786F is available in three grades – 36+, 60+ and 80+ – and widths including 3/8”, 1/2” and 3/4” as well as lengths of 13”, 18” and 20.5”.

The exceptionally fast cut and long life of 3M ceramic abrasive grain enable this slim belt to accomplish a remarkable degree of work. Its fast cutting action helps eliminate burning or other forms of thermal damage, as well.

About 3M Cubitron II and Precision-Shaped Grain

3M Cubitron II abrasive discs, cutoff wheels and file belts have raised the bar for high-performing abrasives. Cubitron abrasives feature Precision-Shaped Grain (PSG) technology, which allows 3M engineers to control the geometry of the abrasive grain for a truly fast, efficient cut. Instead of simply crushing the abrasive into particles, 3M uses microreplication to uniformly size ceramic grains and precisely shape them into triangular structures – essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. What’s more, PSG fractures during use to maintain sharp abrasive edges. The result: Cubitron II cuts 30% faster and lasts 2x longer than conventional ceramic abrasives.

An Alternative to Spot Weld Drilling

The 3M File Belt Sander and 3M Cubitron II File Belt 786F are a great addition to body shop tool rooms. They are a vastly superior alternative to spot weld drilling.

In addition a traditional spot weld drill goes back on the shelf. The versatile file belt tool can also be used for other jobs.
