Toko EVO Power Edger with Fine Grit Diamond Disc
- The ultimate edge tool at the optimum price!
- Easy dial-in edge angle settings from 85 and 90 degrees.
- Includes: EVO power edger; Fine grit diamond disc; Instruction booklet in multiple languages.
- The diamond disc quickly exchanged with no tools required and is backed by a steel spring to ensure consistent pressure throughout the edge length.
- Use any voltage from 100 to 240V. You can use it in Australia, Europe, etc. The tool ships with a standard 3-prong North America plug, all you need is a plug adapter to use in other countries.
- Includes (1) Fine Grit Diamond Disc.
- Sidewall planing is recommended prior to use. Watch the product video below for demo. Go to diamond disc product page for a video on disc selection.
- Not Included are Extra Fine, Medium and Coarse Grit Diamond Discs. These are purchased separately.
- Masks and eye protection are recommended. The EVO produces a fine metal dust when grinding.
- After several uses the EVO pro edger should be cleaned and the spring loaded shaft should be lubricated with 3-in-1 oil or bike dry chain lube (see video in Tuning Tips section of RaceWax website).
From Ski Forum: It has some neat features. Durable diamond grind wheel. Adjustable edge angle from 90 to 85 degrees. Plugs into 120 V AC, but power supply changes it to 18 V DC for the grinder motor. Compact and well balanced. Puts a freaking unbelievable sharp edge on, with minimal hanging burr. Easy to knock off burr with hard gummy to clean up base edge. Diamond wheel is spring loaded, and tool has built in stops, so you can not over-grind edge, unless you do something stupid like holding it in one spot. Keep it moving down the edge, and it takes off minimal metal, especially with the fine grit wheel.
If any of you are wondering why these power edgers make a sharper edge than anything you can do by hand, it is because they swipe across the edge, not along the length. Think about how a barber sharpens a straight razor.
Negatives: Makes grinding dust just like the big boys do. Play it safe and wear a mask. You can pick up a mask at any hardware store. Most of the grind residue is heavy (not like sawdust that floats around) so it falls directly on the tuning bench and can be wiped up with a damp rag. Use the same precautions as you would use with any power tool. Not as heavy duty as a Snowglide, but this was designed for personal or race family use, not all day shop use. Swix claims the average user can get several seasons out of one wheel. I have used it on at least 20 skis, and it appears that the wheel has minimal wear.
The coarse wheel would be used for initial edge set up or remove heavy rock damage. Everything else I would finish off with the fine. If your edge angle is set, and the sidewall pulled, you often only need one pass with the fine to get an incrediblly sharp edge. Check/remove the hanging burr, and you are done!
This is a game changer in two ways. One, you don't need a tool box full of different files, guides, or stones. If you have all 3 grit wheels, which take just a few seconds to change out, you could get away with just the grinder and a sidewall puller. Second, you can not duplicate the edge sharpness with hand tools no matter how hard you try and how long you take.
Don't worry about downward pressure. The disk shaft is spring loaded, so it will always exert the proper pressure for the diamond disk to contact the edge.
Find a way to hold it to maintain constant side pressure on the ski base. It doesn't matter if the ski base is facing away or towards you. Either way works for the grind. Find which base direction works best for you. Maintaining constant side pressure is critical to ensure that the edge angle stays consistent, just like with a hand guide.
Don't start the grinder until you have it set on the ski with solid pressure against the base. It is hard to line it up to the edge if it is running before you have it set against the ski. If you set the grinder against the ski first, then hit the power switch, it is super easy to use.
There is an arrow on the unit that shows the direction to move the grinder along the edge. The arrow also locates the edge of the wheel diameter. This makes it simple to locate on the edge where the grind will start. For example, if I am doing a tip to tail grind, I set the grinder against the base so the arrow is at the transition where the edge curves up to the tip. Once set, I hit the power switch, move along the ski at a steady rate, then let the grinder slip off the back of the ski where the edge curves around the tail. I then flip the ski and grind the second edge in the same way, except the travel is tail to tip.
Find a way to keep the low voltage power cord out of the way. At first, I was hanging it above the tuning bench, but I also found just wrapping it around one of your arms works just as well.
The EVO doesn't use diamonds in their grinding wheels. They use CBN (cubic boron nitride) a synthetic super abrasive developed by GE that is better than diamond for grinding hardened steel. It is just as hard as diamond, but doesn't transfer heat to the metal as it grinds. The CBN is an excellent heat absorber, so the wheel absorbs any heat from the grinding process. No need to wet the disc.
After several uses the EVO pro edger should be cleaned and the spring loaded shaft should be lubricated (see video in Tuning Tips section of RaceWax website).
Great product, works great, nice addition to my snowboard tuning kit.
