Power tool research and data

01What research does AccessoryFit publish?

Each page leads with its key findings, shows the data in tables and charts, explains how it was produced and offers the raw files to download.

• Power tool injury statistics (US)Emergency department injuries by tool, body part, age and year, from CPSC NEISS.
• Table saw injury statisticsBench and table saw injuries, amputations and guard findings.
• Angle grinder injury statisticsGrinder injuries, with the eye and hand breakdowns.
• Power tool battery fire statisticsUS recalls of tool batteries and chargers for fire and burn hazards.
• Power tool noise levelsPublished sound levels by tool type, and what they mean for hearing protection.
• Silica dust statisticsExposure from cutting and drilling concrete and masonry, and the limits that apply.
• Power tool accessory importsWhere the blades, bits and abrasives sold in the US are made.
• Hand-arm vibration exposure calculatorWork out daily vibration exposure from tool figures and trigger time.
• Printable chartsDrill, tap and grit charts as PDFs for the workshop wall.
• Accessory diagramsLabelled diagrams of shanks, arbors and blade parts, free to reuse.

02What are the headline figures in each dataset?

• About 195,900 injuries involving power tools were treated in US emergency departments in 2024 (4.2% of them amputations); see power tool injury statistics.
• 10.9% of US emergency department injuries involving table and bench saws in 2024 were amputations; see table saw injury statistics.
• The eyeball was the body part hurt in 48.3% of US emergency department injuries involving workshop grinders, buffers and polishers in 2024; see grinder injury statistics.
• CPSC announced 9 recalls of cordless tools, battery-platform outdoor tools or tool packs for fire, burn or overheating hazards from 2015 to 2025; see power tool battery fire statistics.
• Circular saws had the highest median sound power of any tool type in NIOSH measurements of 143 tool models, at 109 dBA sound power (median, loaded); see power tool noise levels.
• US death certificates recorded silicosis in 620 deaths from 2018 to 2024; see silica dust statistics.
• China's share of US drill bit imports (HS 820750) went from 43.0 to 22.8% from China between 2021 and 2025; see accessory import data.

Each figure carries its population, place and year on the linked page, with confidence intervals and caveats.

03Why does a fit guide publish injury and safety data?

Because the accessory is often the part of the tool that touches the work, and the person. AccessoryFit exists to answer which blade, bit, disc or pad fits which tool, and fit is a safety question as much as a convenience one: a disc rated below the grinder's speed (see angle grinder disc ratings), a blade with the wrong bore, or an SDS bit forced into a keyed chuck can all fail in ways that hurt someone. The research pages put numbers on the risks that sit behind those fitting rules, so readers can see where injuries actually happen rather than relying on anecdote.

The headline figure, from the US power tool injury statistics, is that about 195,900 injuries involving power tools were treated in US emergency departments in 2024. That page, and the more detailed pages for table saws and grinders, break the total down by tool, body part and age, and are careful about what the data cannot show, such as where most injuries happen.

The other datasets follow the same logic. Battery recall data helps owners of cordless platforms, and anyone weighing cross-brand battery adapters, understand the fire and burn hazards that have led to recalls. Noise and vibration figures matter to anyone who runs a grinder or hammer drill for long stretches. Silica dust data is directly tied to the choice of diamond blades for concrete and SDS rotary hammer bits, and to using dust extraction with them. Import data answers a question buyers ask often: where are these accessories actually made.

04How is the research done?

Every dataset is built from published primary sources: government injury surveillance (CPSC's NEISS), recall notices, NIOSH and HSE measurement databases and guidance, peer-reviewed studies, and US trade statistics. Where AccessoryFit produces its own estimates, for example by summing NEISS case weights into national totals, the method is written out on that page, including how confidence intervals were calculated and which estimates fall below CPSC's reliability thresholds and are therefore not quoted.

Nothing on these pages comes from product testing, and no figure is rounded up or recast to sound more dramatic. Where a change between years is within the margin of error, the page says so. Where two sources disagree, both are shown. Figures from a single study name the study and its population in the same sentence, so they are not lifted out of context. The general sourcing, conflict and correction rules for the whole site are on the AccessoryFit methodology page.

Each research page lists its sources in plain text at the bottom. Pages are reviewed when new data is released; NEISS, for instance, publishes a new year of data annually, and the injury pages will be refreshed when it does.

05Can you reuse AccessoryFit data and charts?

Yes. The data, tables, charts and diagrams in this section are free to reuse, including in commercial work, under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). The only condition is credit to AccessoryFit with a link to the page the material came from. You can redraw the charts in your own house style, translate them or crop them, as long as the credit stays. Product photographs and third-party images are not covered by this licence.

Each research page built on a dataset has a downloads section with CSV files and full-size PNG charts (the silica page summarises published studies and has no download), so you can check the numbers or build your own chart rather than copy a screenshot. Diagrams are available as WebP and, where possible, SVG.

06How should you cite AccessoryFit research?

Use the page title, the last-updated date shown at the top of the page and the page URL, for example:

AccessoryFit, "Power tool injury statistics (US, 2015–2024)", updated 22 October 2026, https://accessoryfit.com/research/power-tool-injury-statistics/

Where a figure comes from a government source such as CPSC NEISS or from a named study, it helps your readers to name that source too; each page states which source a figure rests on. For a chart, a credit line such as "Chart: AccessoryFit, CC BY 4.0" with a link to the page is enough. Journalists, teachers and safety writers who need a breakdown that is not on the page, or who spot an error, can use the contact page; corrections are made on the page and noted with a new updated date.
