  • Useful kit.
Size: 1/4" Cutting Dia Style: 3 Pieces
This is a good kit if you want all three of the different cutting patterns in a kit that gives you a discount for buying in a set. Individually these will be more expensive. The machining on these is tight. Smooth shanks, clean spirals with consistent edges. Sharp (but not excessively sharp) tips. I can't rate the blue coating and in general I need to run these before giving a proper review. ... show more

  • A little pricey but good quality
Size: 1/4" Cutting Dia Style: 3 Pieces
I was a little skeptical about these bits at first because the price is somewhat higher than other similar items but I was pleasantly surprised about the quality of the bits. The coating on them is top notch, the flutes are very sharp and dimensions are right on the money. I used the compression bit the last few days and it performed flawlessly creating a crisp groove / mortise on my workpiece for a tongue and groove joint. ... show more
