Drill AmericaDWTB30X3.5 m30 x 3.5 High Speed Steel Metric 4 Flute Bottoming Hand Tap, DWT Series

Arrived in a very nice plastic case. The tap was clean, sharp and nicely manufactured.Had to drill out 2 stuck screws and then clean the threads. Wasn’t sure how well it would work, but it exceeded all my expectations.This is a very nice tap! Excellent!

Ordered this tap to cut threads in a through-hole rotor shaft so the rotor could be removed with a forcing screw. The tap arrived in a small, clear plastic case inside of a plastic bag. Nifty little case for storage. The tap's fit and finish were excellent with sharply defined threads throughout and a very nice gradual taper to start. It alligned and cut the threads smoothly and with ease. I used a Lisle tap socket and ratchet to drive it with 80W-90 gear lube for cutting oil. I'm very pleased with the tap and would definitely order another Drill America tap or drilling tool when the need arises.

Uncommon tap size to find. I usually order tools like this from McMaster Carr but they didn't have it. I used it on my VW Solex carburetor after I stripped a thread in the housing. Used JB Weld to fill the hole, then drilled and re-tapped the hole with this tap. Worked great.

Excellent set of taps for starting and bottom threading blind holes. Strong taps, very sharp. Accurate threads. I use these to cut plug threads in hardened steel crankshafts. The taps laughed at cutting threads in forged steel..

Cut well but bottoming tap snapped under moderate load.

I had to rethread my lug nuts and it worked like a charm!

I was installing a tow hitch on our vehicle, and the bolt holes had some corrosion and Road grime preventing the bolt from biting. So I used this to chase the threads and installation was easy after that! This size wasn't available in the kits I looked at, so I was happy to see it here.

I messed up a thread on my vehicle and this product was the tool for my repair.

Great product, fast shipping, thank you so much.

Mi sono arrivati tre terzi maschi con smussature differenziate nella punta, il prodotto è valido, non loconsiglierei a chi deve filettare acciaio.

Hace correctamente la función para lo que fue diseñado.

It came in the usual plastic cases for taps, which some sellers don't include, and works suitably on aluminum.

la punta venia sin finalizado, no se podía trabajar bien en el torno, hubo que adquirir una nueva en otro lugar, decepcionante
