How to Use

TEMCo TH0004 Knockout Punch Step 2
TEMCo TH0004 Knockout Punch Step 3
TEMCo TH0004 Knockout Punch Step 4

STEP 1 Install the correct punch mandrel on the hydraulic cylinder along with the female portion of the punch die.

STEP 2 Drill a pilot hole large enough to clear your selected punch mandrel.

STEP 3 Insert the punch mandrel through your drilled hole in the panel. Install the male portion of the punch die by threading it down to the point where it is snug against the metal to be punched.

STEP 4 Close pump valve and pump the handle until the punch is drawn through the metal. Release the pump valve and remove the punch dies.

Selecting a Back-up or Replacement Draw Stud

We're constantly improving our products, and our hydraulic knockout punches have gone through a few iterations over the years. As such, if you purchased a hydraulic knockout punch set from us a before a certain time, you're going to need a specific draw stud. Here's a quick guide to help.

TH0004 Draw Stud Selection Flow Chart

Includes the TH0357 M35 Cobalt High Speed Steel Step Drill Bit

Designed Specifically for Electricians. TEMCo Industrial's long 3/16" steps properly drill holes sized for common draw studs on your conduit knock out punch set. That means no more going in through the other side or oversizing your hole just to get the draw stud in.

Cuts Fast! - Impact Driver Ready. Never used an impact driver on a step drill bit before? You're missing out - if you need to punch out a bunch of conduits, this is a huge time saver. If you're just using a regular drill, that's ok - the hex shape makes sure the bit isn't slipping on the chuck.

Not all "cobalt" high speed steel (HSS) step drill bits are made the same. The business end of our bits are made from high quality M35 Cobalt HSS. Other high speed steels that don't contain cobalt, like M2 HSS, have much lower rated "red hardness", which means more wear at higher temperatures. M35 HSS is also rated to be tougher than M42 HSS, which also contains cobalt. That means our steel properties are balanced to keep a sharp edge, even when it's heating up, so it can keep up with your hard work. We've also taken the time to add a second flute, which means double the cutting edges and halving the time it takes to drill that hole. A second flute also means the wear is evenly distributed across two flutes instead of just one, also increasing the lifespan of the bit.

Uncoated or Titanium Nitride? TEMCo's step drill bits currently come uncoated (Part Number: TH0357), or coated with Titanium Nitride (Part Number: TH0356). The added layer of Titanium Nitride is primarily to increase the bit's abrasion resistance, adding the ultimate layer of protection to an already robust step drill bit, therefore increasing the wear life.

Cheap drill bits are frustrating to use, easily wear out, and produce poor quality work that reflects on your craftsmanship. Get the job done right and make sure you have a TEMCo drill bit to accompany your knockout punch set.
