| OUR CHOICE | Designed to handle larger drill bits up to 3/4″, ideal for sharpening 3/32″ to 3/4″ bits with one chuck, compatible with any angle from 115 to 140 degrees. Alignment of bits over 1/8″ is done with the chuck by inserting it with the bit into the alignment slot. With bits smaller than 1/8″, you have to insert the bits into the alignment slot without the chuck initially and then slide the chuck over the bit after. You can also use it to convert standard point bits to split point bits. After sharpening, the tips of carbide masonry bits seem to have a more angular look than the original tip, but they work excellent. Most bits took well under one minute to complete, and I wasn’t even hurrying. Almost all came out right on the first try. Any mishaps where easily fixed by simply repeating the procedure over again. It’s safe to say that most bits in reasonably good shape can probably be sharpened at least eight to ten times. One of the biggest and probably the most overlooked advantages of the 750SP is that it can also sharpen up to – SDS type masonry bits. Supposedly you can get about two hundred sharpenings from one grinding wheel. Replacements grinding wheels cost twenty dollars and come in 100 grit or the standard 180 grit. It works extremely well and requires a minimal learning curve. Additionally, having sharp drill bits readily available can go a long way toward helping reduce job productivity losses. | |

When you first get it, sharp several high-speed steel (HHS) ½ bit for practice. If you have split point or like split point bits, better get the xp or 500x. Clean the chuck often. Make sure to watch the 7 min. video before your first try. DD350X does not grind drill bits into the convenient split end shape, higher models do that. Product works well with metal and carbide bits. The only difficulty is with the small 3/32 bits. This will just take a little more practice. | |
| | Grinds and sharpens 1/8″ – 3/4″ bits. Does a fine job and it is a lot less expensive than a Drill Doctor. This tool works well with bits larger than 1/8 inch. It works, but unless you understand all of the different angles of a drill bit tip and how to line the bit up with the face of the grinding wheel to achieve the shape you desire then I suggest going with something like the drill doctor to save yourself hours of frustration. |
