worth the money
for the money these bits are a good buy . cut good , last as long as any other brand . they're not as pricey as carbide and won't last as long . but for a home shop they are the best buy you will find . i recommend them highly . ... Read more

Junk!
I ordered this set to replace the one that came with my mortiser. The original had cut probably 80 inches of 1" deep mortises. I expected that because it was "Austrian" that the Quality would be better. NOT! The amount of metal in the bit is roughly 1/3 the metal in the OEM bit. I should have known better,I put it in the Machine and made just two cuts before it snapped. I will be calling Delta in the morning to find out if they have anything available that will match the OEM Ouality. Tool crib customer Service could not tell me.

Poor Durability
First unit lasted 10 mortise cuts (3/8" deep)in red oak before bit broke. Unable to find replacement bit, bought second set to finish job. Bit lasted 12 mortises. If it is this fragile, replacements need to be readily available. I am not a rookie. This was not abuse of the tool.

replacement bits
The product appears to be of good quality, but the bit is the weak link. And I haven't been able to find replacement bits. The tool catalogs only list the bit/chisel sets. Where can one buy the replacement bits?

1/4" Mortising Chisel Set
This product delivers what it promises consistantly. The only problem with it is that unlike my 5/16" bit set, this bit is easy to snap in hardwoods like maple, even when adjusted to the manufacturers specifications. To compound the problem, it is hard to locate the replacement bits that are advertised on the side of the packaging. I recommend taking time to clear this bit of any debris between every cut to avoid causing the bit from snapping due to clogging between it and the outer chisel. ... Read more

Austrian Bits are the Best
This mortising chisel and bit is finely crafted in Austria and although expensive, it is worth every penny. I have built several beautiful pieces of furniture without incident.Both pieces are of such high quality, that with proper care and sharpening, they can last for years. I would have given it five stars except for the price. (Amazon's price is on par with any hardware or other internet tool store.) ... Read more
