Product Description

The Dormer A097 variable-length, TiN-tipped, general-purpose, round-shank drill bit set, offers a set of drills to drills holes into a wide variety of metals and synthetic materials. It can drill to a depth up to four times the diameter of the drill size. The shank diameter is the same as the drill size.

The A097 series has a type N flute form, with a regular helix (21 to 34 degrees) angle and with a special Dormer PS point geometry which offer easier workpiece penetration, improved hole size, and accurate centering when starting the hole. The TiN finish is a gold-colored ceramic coating that is hard and has low friction, permitting faster cutting speeds than uncoated materials. The jobber length offers a good compromise between reach and rigidity.

This set has the following options: Style 18, tool type A012, number in set 29, and set sizes 1/16 – 1/2 x 1/64; style 20, tool type A012, number in set 15, sizes 1/16 – 1/2 x 1/32; style 60, tool type A012, number in set 13, sizes 1/16 – 1/4 x 1/64; style 12, tool type A012, number in set 60, sizes Nr. 1 – Nr. 60; style 14, tool type A012, number in set 26, sizes A to Z; style 30, tool type A012, number in set 115, sizes 1/16 – 1/2 x 1/64, Nr. 1 – Nr. 60, A to Z.

Size: 1/16-1/2" Verified Purchase
These are great bits. They cut very quickly, and seem to stay on line with no drift. My only comment (for those of you like me who might not be paying attention) is that the drill bit shanks are the same size as the drill bit. What this means is that because I have a 3/8" chuck in my drill, the 4 or 5 largest bits wouldn't fit in my drill. Possible solutions: get a drill with a 1/2" chuck; or take the larger bits to a machine shop and have the shanks turned down to fit a 3/8" chuck (or do it yourself if you're a machine kinda guy). That's not a negative on the bits, though ... just info for the savvy shopper. The bits themselves are excellent.
