Marples 1-1/2" Forstner bit
This bit cut very cleanly and easily into end grain of walnut
Works great!
Right out of the packaging this forstner bit worked exactly like I needed it to. it cuts nice clean, smooth holes, with minimal sanding afterwards. Will definitely look into purchasing more Irwin Marples forstner bits if I need additional sizes.
A BIT of greatness.
Would RecommendBest drill bit I’ve ever bought. I was making so, me cap racks for my daughter who was giving them as Christmas presents. They included drilling 10, 1-1/2” holes in a 3 ft 2x4 times 6, after the first try with my cheap foreign forstner bit set, I gave up and went to Lowe’s and grabbed a new marbles bit. It took me longer to go to Lowe’s and back than it did to finish drilling the other 50 holes, I was amazed! I’ll never use any forstner bit but a Marples, fastest, smoothest holes I’ve ever dri...

Sharp right out of the package
Would RecommendIt was extremely sharp and cut through hard maple with ease.
I would buy again if I needed
Would RecommendIt drills a nice clean flat hole but it is slow , every drill bit whether spade bits forstner bits their slow but they make a smooth hole. I'm making a project that needs smooth bottom holes.
Not good if you’re looking for something precise
Would Not RecommendBought two of these at the same time and the diameter of the holes drilled by the bits are off by about 1/8” from each other.
Size is incorrect
Would Not RecommendWhile I genuinely like Irwin products, this one was extremely disappointing. The size was off by 1/8” dispite being label as 1-3/8” 34.9mm. The actual measurement was 1-1/4”. Others on the site verified the mislabeling, both on the package and the incorrect marking on the shank of the forstner bit itself. Just wish I checked before I set up my cabinets work. Going to another place tomorrow and buy another brand. Can’t trust Irwin any longer. PS: IRWIN Customer Service, please don’t ask m...
