CRAFTSMAN CMHT82547 vs KNIPEX 00 31 20 V01 US: Compare the Included Sizes and Adjustment Controls

Both sets list a 10-in plier, but their second tools differ: 8-in Groove Joint for CRAFTSMAN and 7 1/4-in Cobra for KNIPEX. CRAFTSMAN identifies its joint type, while KNIPEX documents button adjustment directly on the workpiece. Match the included lengths to your planned work and choose the identified adjustment design that fits your preference. These are feature-fit distinctions, not tested performance results.

The buying question

Do the listed tool lengths and the manufacturers’ identified adjustment designs fit the buyer’s planned work and preferences?

Both sets include a 10-in plier, but CRAFTSMAN pairs it with an 8-in Groove Joint plier while KNIPEX pairs it with a 7 1/4-in Cobra. CRAFTSMAN identifies the joint type; KNIPEX documents button adjustment directly on the workpiece.

Quick verdict

When to skip: Your job requires a 12-in plier in the included set; neither of these exact two-piece bundles lists one.
When the recommendation changes
  • Your required second tool length or fitting dimensions differ from the set contents; nominal tool length alone does not confirm jaw opening or fit.
  • You need the CRAFTSMAN adjustment steps or position count before buying; its exact product page does not provide those details.

The differences that matter

Supplied Tool Lengths And Set Fit

CRAFTSMAN CMHT82547 8-in and 10-in Groove Joint Pliers Set

Two pliers: 8-in and 10-in[1]

KNIPEX 00 31 20 V01 US Cobra Water Pump Pliers Set (7 1/4-in and 10-in)

Two pliers: 7 1/4-in and 10-in[2]

What this changes: Both sets list a 10-in plier, but the other nominal tool length differs; buyers can match the listed pair to their planned access without treating length as a jaw-opening or fit measurement.[1, 2]

The better fit depends on your priorities

Jaw Adjustment Workflow

CRAFTSMAN CMHT82547 8-in and 10-in Groove Joint Pliers Set

KNIPEX 00 31 20 V01 US Cobra Water Pump Pliers Set (7 1/4-in and 10-in)

The exact manufacturer page identifies a Cobra Water Pump Pliers set and documents adjustment at the touch of a button directly on the workpiece.[2]

The better fit depends on your priorities

Limitations

  • The listed tool lengths do not establish jaw opening, working reach, or whether either plier fits a particular fitting.
  • The CRAFTSMAN page identifies Groove Joint pliers but does not provide adjustment steps or a position count; do not infer those details or assume the tool lacks a similar control.
  • No controlled tests were conducted for grip, force, slippage, speed, durability, or safety; no performance winner is claimed.
  • KNIPEX lists 00 19 55 S8 as a separate three-piece tool-roll set. Check the part number: this comparison concerns the two-piece 00 31 20 V01 US set.

Questions shoppers ask

Do both sets include a 10-in plier?

Yes. Both manufacturer pages list one 10-in plier. The second tool is an 8-in Groove Joint plier in the CRAFTSMAN set and a 7 1/4-in Cobra in the KNIPEX set.

What adjustment details are documented for these sets?

CRAFTSMAN identifies the CMHT82547 tools as Groove Joint pliers but does not specify steps or positions. KNIPEX documents adjustment at the touch of a button directly on the workpiece. The available CRAFTSMAN page does not establish whether it has a similar button control.

Does the nominal tool length confirm whether a plier fits a particular nut or pipe?

No. The listed length pair identifies the included tools, not their jaw opening or fit for a particular fitting. Check the exact fitting requirement before choosing.
