The best tamper plate for a jackhammer is one that matches the tool’s chuck size and suits the material you need to compact. These five 6-by-6-inch options are intended for tasks such as tamping dirt, sand, and gravel. The XtremepowerUS attachment is a straightforward 1-1/8-inch option, while the YOSIGHT model specifies heavy-duty 40Cr steel. JACKCHEN, HIGOSPRO, and Monkey King Bar list 30mm or 1-3/16-inch-style shanks, so check the exact product and hammer specifications before choosing.
| Product | Listed shank size | Best suited for |
|---|---|---|
| XtremepowerUS | 1-1/8-inch hex | Buyers needing a listed 1-1/8-inch fit |
| YOSIGHT | 1-1/8 or 1-3/16-inch stated | Buyers prioritizing 40Cr construction |
| JACKCHEN | 1-3/16-inch (30mm) hex | Buyers with a matching chuck |
| HIGOSPRO | 1-3/16-inch (30mm) hex | Buyers seeking a heat-treated steel set |
| Monkey King Bar | 30mm / 1-1/4-inch stated | Buyers who verify the listed fit first |
XtremepowerUS 1-1/8-Inch Hex Tamper Plate
This attachment pairs a 1-1/8-inch hex shank with a 6-by-6-inch compaction plate. The listed uses include tamping loose granular soil, sand, dirt, and gravel, as well as landscaping and asphalt-related work. The product description says the shank and plate are made using a forging process and describes a solid construction intended for impact work.
Best for: Buyers whose jackhammer accepts a 1-1/8-inch hex shank and who want a compact plate for small-area leveling or foundation preparation. It was selected for its clearly stated size and range of listed uses. Check before buying: Do not assume this fits a 30mm or other hex chuck; confirm the hammer’s required shank size.
YOSIGHT 40Cr Steel Tamper Plate
YOSIGHT lists a 6-by-6-inch plate made from forged 40Cr chromium steel, with high-temperature quenching and one-piece construction. The description gives a standard 1-1/8-inch or 1-3/16-inch hex-shank specification and calls for matching the attachment to the hammer’s chuck. Its flat plate is intended to compact soil, gravel, sand, dirt, and asphalt.
Best for: Buyers who value the stated forged, heat-treated steel construction and need a 6-inch square plate. It was selected for its detailed material and use information. Check before buying: The listing presents two shank-size specifications. Confirm which size applies to the item you are ordering and compare it with the jackhammer manual.
JACKCHEN 30mm Hex Tamper Shank
JACKCHEN specifies a 1-3/16-inch, or 30mm, hex shank and a 6-by-6-inch plate for soil and gravel compaction. Its listed material is chromium-vanadium steel, described as resistant to abrasion, oxidation, and corrosion. The product is presented as a tamper attachment for electric or gas-powered demolition hammers with the matching chisel locking system.
Best for: Buyers whose hammer specifically takes a 30mm hex shank and who want a plate for compacting soil or gravel. It was selected because its shank dimension and material are explicitly stated. Check before buying: “Universal” in a product description does not mean every jackhammer will accept it; verify the chuck and locking requirements.
HIGOSPRO 30mm Heat-Treated Tamper
This HIGOSPRO set has a 6-by-6-inch plate and a listed 1-3/16-inch (30mm) hex shank. The product description says the steel is forged and heat-treated, and identifies loose granular soil, dirt, gravel, and sand as suitable materials. Its compact structure is intended to hold the shank and plate together during tamping.
Best for: Buyers with a 30mm-compatible jackhammer who want a listed forged and heat-treated steel attachment for small compaction jobs. It was selected as another clearly described 30mm option for comparing construction and intended use. Check before buying: The listing does not provide a different plate size; buyers needing broader coverage should compare the 6-by-6-inch footprint with the work area.
Monkey King Bar 17-Inch Tamper Attachment
Monkey King Bar describes a 17-inch tamper bit with a 6-by-6-inch plate and forged, heat-treated 40Cr steel. Its stated uses include tamping loose granular soil, gravel, and sand, with applications in construction, landscaping, and paving. The shank-size information is inconsistent: the name refers to 30mm, while the features also state 1-1/4-inch hex.
Best for: Buyers considering a longer listed attachment for tamping granular materials who can confirm the exact shank dimension with the seller. It was selected for its stated 40Cr construction and broad use cases. Check before buying: Resolve the 30mm versus 1-1/4-inch specification before ordering; those measurements are not interchangeable.
Buying Guide: How To Choose A Jackhammer Tamper Plate
Which shank size fits your jackhammer?
Match the attachment’s hex shank to the jackhammer’s chuck and bit-retention system. Common dimensions in these listings include 1-1/8 inch and 1-3/16 inch (30mm). A product that looks similar may still fail to fit if its shank is too large, too small, or incompatible with the tool’s locking system. Check the manual or measure the existing bit before ordering.
What plate size and shape do you need?
All five options list a 6-by-6-inch plate. A square plate is suited to compacting relatively small areas and reaching corners, but the listed size means repeated passes may be needed for larger sections. Consider the work area and whether the plate can be controlled safely with your hammer.
Which materials can these attachments compact?
The product descriptions most consistently name loose soil, dirt, sand, and gravel. Some also mention asphalt, landscaping, paving, or construction. These listings do not establish that every attachment is appropriate for every surface or job, so follow the jackhammer manufacturer’s instructions and the requirements of the project.
Does steel type determine the right choice?
Material descriptions can help compare listings, but they are not a substitute for correct fit. YOSIGHT and Monkey King Bar specify 40Cr steel; JACKCHEN lists chromium-vanadium steel; HIGOSPRO describes forged and heat-treated steel. Compare the stated construction, then prioritize shank compatibility and intended use.
Frequently Asked Questions
Can a tamper plate fit any jackhammer?
No. The shank size and locking system must match the jackhammer. Verify the chuck specification before purchase.
What is a jackhammer tamper plate used for?
It transfers impact from a compatible jackhammer to a flat plate to tamp materials such as loose soil, sand, or gravel.
Is a 30mm shank the same as 1-1/4 inch?
No. The listings use both measurements, but 30mm is approximately 1-3/16 inches, not 1-1/4 inches. Confirm the exact specification for the product and tool.
Are these plates intended for concrete breaking?
They are described primarily for compaction. Use a breaker bit designed for concrete demolition when the task is breaking concrete.
