What the CPSC Data Shows

Power Workshop Grinders, Buffers Or Polishers (CPSC product code 897, in the Home Communication & Entertainment category) generate an estimated 8,401 emergency-room visits every year in the United States, adding up to roughly 159,621 ER-treated injuries across the 19-year span from 2006 to 2024. PlainSafety derives a danger score of 36/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are declining by about 15% over the last five years, with the busiest year on record being 2016 (11,751 estimated ER visits) and the quietest 2006 (4,407 estimated visits).

The single most common ER diagnosis for power workshop grinders, buffers or polishers is foreign body to the eyeball, accounting for approximately 51,660 visits across the 20-year NEISS window, followed by laceration to the finger (26,500 cases). The 35-44 age group absorbs the largest share of injuries, about 32,957 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 3.1% of ER visits involving this product end in hospital admission or transfer, and a small fraction (0.06%) result in fatality.

Beyond the hospital-sampled NEISS projections, this page also aggregates 29 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how power workshop grinders, buffers or polishers fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Consumer Incident Reports

Reports filed by consumers on SaferProducts.gov.

9/25/2013 · Injury, Hospital Admission · Harbor Freight Tools · Texas

Was beginning to grind piece of metal with a handheld drill master die grinder. The blade chipped & the grinder flew out of my hand into my ankle. It cut through tendons. This tool does not power off when it comes out of your hand. I had to reach over to turn the switch off. I had surgery Sunday evening to repair tendon after pieces of the blade were removed from my ankle. Handheld tools should all have a safety feature and should power off immediately if not being held.

The submitter is reporting the unit for posing an injury hazard. She said during the first use the unit fell apart in three pieces. She indicated that it occurred while sharpening an object at 3300 RPM. She sustained a laceration on her left thumb but she believes the injury could have been worse if she had not been wearing protective gear. At the ER they stitched her wound and took x-rays. Her son sent a letter to the firm reporting the incident. She said the firm has not yet responded.

9/21/2018 · Incident, No Injury · Metabo Corporation · Georgia

While using the Metabo grinder the switch was released to stop the blade but the tool kept running. In reaction to this the operator somewhat lost control and the blade struck a steel member causing the blade that was still under full power to come into close proximity of the operators body in what is being considered a near miss in bodily harm by a hand power tool. No injury occurred.

9/15/2015 · Injury, First Aid Received by Non-Medical Professional · Harbor Freight Tools · Mississippi

On 8/30/15 I was using this grinder with wire brush attachment cleaning out a tank for my boat. The auxiliary handle broke, the grinder kicked up catching me in the face and chest. The machine didn't shut off and I had to pull the plug out of the socket to stop the machine. The handle that broke is very thin construction and may have been flawed. The on-off switch does not automatically shut off when released (as OSHA standards may require). The on-off switch is located on the motor. The motor gets hot making it hard to hold on to this tool securely. Luckily I had the wire brush on this tool and not a grinder or cutting blade. Otherwise, instead of just bruising and scrapes the blades would have cut through my cheek and chest and I might not have been able to cut it off by pulling the plug & I would have been dead. Note: Item was being used IAW owner's manual and safety instructions. See Attachments: A, B and C.

Bought a Porter Cable PXRA2676KIT Multi Surface Restoration Tool Kit. Upon using it it started to make grinding noises. Then sparks flew out where the sanding drum is then hot metal parts flew out. Luckily I was wearing safety glasses. I was able to save one of the pieces that flew out. The other one is lost in the yard. I am trying to contact Porter Cable buy so far have only been put on hold. The part appears to be part of the main housing, is metal and was ripped out of the plastic housing by the action of the sander. The parts that came out are a piece of metal rod approximately 1/4 in diameter by 3/8 inch long.

7/18/2015 · Injury, Emergency Department Treatment Received · Harbor Freight Tools · Ohio

I was using an angle grinder with a brand new Harbor Freight cut off wheel. Half way through the metal pipe the wheel came apart in about 6 pieces with one of them flying back at my hand cutting my right index finger at the knuckle that required 8 stiches

7/1/2019 · Injury, No First Aid or Medical Attention Received · Harbor Freight Tools · Tennessee

4.5" Angle Grinder from Harbor Freight the weld on the metal guard keeps breaking. This the 3 or 4th one I have bought and the guard breaks while in use. Also, there is something wrong with the internal safety mechanism. The grinder will shut off during usage and if you don't remember to turn it off it will intermittingly turn on while hanging on tool hook or holding.

6/30/2014 · Incident, No Injury · W.W. GRAINGER, INC. · New Mexico

At an Ironworkers Shop here a trained ironworker secured the WESTWARD twist wheel 4” stainless steel onto a [REDACTED] grinding tool. The max rpm of the wheel is listed as 20000 and the grinding tool lists the max rpm of 12000. Upon the beginning of the grinding operation the wires from the WESTWARD began to become released from their source. The ironworker fortunately was wearing all of the appropriate PPE and was not injured in any way. The worker removed the first wheel, inserted a second wheel from the order of 48 and the same result occurred. A significant portion, 43 to be exact were returned to the local supplier (Grainger) before I was made aware of the situation so I only have three currently in my possession. I spoke to the Albuquerque Grainger Rep, then Grainger International, who then could only offer me to file a “customer concern” and that my reporting of this disengaging to the wires was an “isolated incident”. They said that they felt my call warranted only a “customer concern” as it was an isolated incident even though the wirers came off of two out of the 48 we ordered.
