"Cuts easily (Just remember to clean out the hole frequently and keep it lubed) It also has the size stamped onto it, not just "laser etched" that will wear off quickly."

"I tapped a hole in a few different pieces I made to use a shift knob and it performed perfectly."
"Worked great."
"I had selected it in the dropdown, but somehow in the purchase process it reverted to the top item in the list."

Enter your model number to make sure this fits.
Reviews
"After using this bit for about 50 minutes of cut time on a CNC with a conservative feed rate and plunges, this thing broke."
"Regardless of what kind of power tool you are using, there is one universal truth: if you install a Freud blade (or bit in this case), it will perform better. I needed to do something with my new router, and the only bit I could fine was a dull / burnt, steel, off-brand bit I had laying around."
"I needed to cut some slots for tiny loose tenons in some doll furniture and this worked great on oak, cherry and maple."
"I've tried couple other brands, they all break when pushed too hard."
"In the week that I have had it, it has cut arches out of 1/2" CDX plywood, curved template cuts out of 1/2" Birch ply, mortised for concealed joist hangers in old growth cedar 4x6s and is still as sharp as when I took it out of the box."
"Combined with the dust collection system on my OF1400 EQ, and it was amazing how clean the job was cutting through plywood."
"deep mortises), router bits such as Whiteside or CMT, are better choices."
"I was cutting a 1/4" deep dado through pine at 12,000rpm with a very conservative feed rate and it just snapped."

"My RV hot water tank anode rod boss threads were corroded to the pint that I could not start the first thread of a new replacement rod. On potable water systems do not use oil or thread lube unless it is a new cut and able to wash with hot soapy water and clean rinse."

"I used this tap to make threads in an aluminum housing."
"I received this tap yesterday to finish a Pressure to Force Gauge for my hydraulic press and found a pleasant surprise in the bag, X2 of them!"
"Better than the cheaper taps, but better quality is not always needed."
"My aftermarket fuel rail came stripped, so we needed to re-tap it."
