Duravit 790108000000000 Multiple Support Frame for Bathtub

Hey there! Thank you for your query on the Diablo DS0914BF15 15-pack 9in reciprocating saw blade. Each blade has 14/18 TPI, as it features a double tooth configuration, which means the alternating teeth come in two (2) sizes. If the smaller-sized teeth were grouped, eighteen (18) of them would fit in an inch, whereas there would be fourteen (14) larger-sized teeth within an inch. We hope this information helps. To purchase, simply click "Add to Cart" and fill in the needed information. Thank you for choosing PlumbersStock! Have a nice day!
