What Customers Are Saying

This set of Forstner bits generally performs well for most woodworking projects, producing clean, smooth holes, especially when used with a drill press. The wide range of bit sizes is a key benefit. However, some customers reported quality issues like dull or damaged cutting edges, as well as challenges using the bits in a handheld drill. Overall, this is a reasonably priced and functional set suitable for hobbyist and DIY use, but may not meet the needs of professional or heavy-duty users.

Will make holes constantly.

Would Recommend

Like the case and the quantity of bits. Down side the bits can slip in the drills chuck. So 4 stars.

Round shank

Would Not Recommend

Should have hex shank. Can't get these bits tight enough so they don't spin in the chuck.

Well worth the price

These forstner bits were exactly what I expected and needed. The machining was second to none, especially considering the price point. I would however recommend these be used in a drill press. The can be easily chucked into a hand drill, but the drill likes to walk around, and I puts a decent burden on the drill/ battery.
