Milescraft1312 Drill Block - Handheld Drilling Guide, Drilling Jig with Drill Guides for 6 of the Most Common Imperial Drill Bit Sizes, Precision Drilling Tool Accessory

works great, if your drilling into corners or for a precision job other than a drill press, this is for you! Build quality is fantastic for home use and the accuracy is great. Very easy to use.

works great; price is supprisingly low

As some others have stated, this has a limited selection of hole sizes, but I knew that when I purchased it. For the price, it's well constructed and useful given that limitation. I don't use it a lot, but it has helped me a few times when I needed more than eyeball precision for a perpendicular hole...didn't need to be perfect, but just more than I'll get on average with eyeballing. the metal sheathing around the hole is durable...I needed to drill a 1/2 inch hole over my head and after getting the bit started, I slid this on the bit, slid it to the surface and was able to hold it well enough by hand. Got a great hole, I can't tell I shaved any metal off the sheath. Good value and glad I have it around--should have got it or something similar a long time ago.

Great idea at a great price.If you need to drill a hole at a 90 degree angle and easy to use.

This is the best tool to ensure your cabinet door pulls have a professional look consistently throughout the entire kitchen and not one that is just "wrong". I am sure there are many other uses, but I bought it for that and it worked perfectly.

Getting old. Never needed aids to drill center or 90 deg before but time always wins. This little tool is cheap and accurate and for this hobbyist/occasional use homeowner it works great.

Handy and affordable alignment toolThis guide is a great budget-friendly way to drill straight holes, especially useful for dowel joinery. It’s not the most rugged option out there, but it performs surprisingly well for the price. A little care in setup and clamping goes a long way. Definitely a useful tool to keep around for occasional precision tasks

This drill guide is probably okay for flat pieces of wood, but to drill into a dowel or other curved surface, it is not very good. It does sort of fit on the curved surface, but not firmly enough to make much help. Even by clamping it onto a dowel, it is still not great.Also, the 1/2 inch hole is too small for a 1/2 inch drill bit, at lease the ones I have.Price is good.Overall, an adequate, but not great tool.My grade a C-
