DrillBlock

Works great

Handy and affordable alignment tool This 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

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.

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.

I never knew this tool existed. It makes drilling into pipe SO much simpler and straight.

Outstanding value for drilling plumb and level holes. Easy to use and durable build quality. It's small size makes it easy to throw in your tool pouch or setup nearby your project. Helps when you need a guide and can't get your work piece in your drill press. The design and light weight is excellent. All of the major bit sizes are included. It's particularly useful when drilling for dowels. No matter where you use it, you can count on the hole to be accurate and alignment to be spot on. This is a good company. They've been around a long time, so you can trust their products to be well made and imitated by others.

This is a great little tool and easy to carry in a tool belt or bucket. I used it to make a shadow gage for aligning my portable solar panels. When I checked the perpendicularity of the post to the base with a square at 6 positions, it was only out by a degree or two at two locations. I also use it for drilling pilot holes for screws when I really need the screw heads to be flush when countersunk into a wood or metal surface.

Great for drilling a straight hole, just took thick to see your mark!

Grips nicely to flat surface. Ensures 90 degree holes in most common sizes. Useful tool and inexpensive. Well made. Would prefer rectangular shape as opposed to wavy shape for easy of jigging for multiple, evenly spaced holes. The wavy shape is user, hand holding friendly, however and that is the intent of the jig. Pressing down locks jig nicely in position without drift. There is the Milescraft drillblock plus version of this jig with more holes in 32 seconds but Amazon does not offer it for sale yet.

Be careful with this. The product picture shows metric measurements in mm which is what I wanted. The actual product received has imperial measurements in inches. I'm not sure if there are two different versions or if the hole sizes are identical on both and they have labelled one slightly inaccurately. I will measure the holes and find out. 1/2 inch would be closer to 13mm than 12mm. *They sent me out a proper replacement quickly to be fair and it is not a bad product. As longas you receive the correct product it is decent.

Lo he estado usando durante muchos meses, y realmente he comprado su utilidad y precisión en perforaciones perfectamente rectas.
