Summer is the season for home improvement. The sun and good weather makes the season perfect for getting things done. But with heavy use comes wear and tear—and that's where replacement parts save the day. Here’s a look at the most popular power tool parts homeowners and pros alike are reaching for this summer.

1. Batteries and Chargers

Cordless tools are a summer staple, and brands like DEWALT, Makita, and Black & Decker dominate backyards and garages across the country. But without reliable batteries and chargers, your cordless drills, trimmers and saws are useless.

• Why they’re popular: With more outdoor projects happening in summer, users need extra batteries to keep tools running all day. Swapping in fresh power lets you work longer without waiting for a recharge.

• What to look for: High amp-hour (Ah) ratings for longer run times, and fast chargers to minimize downtime.

2. Saw Blades

From circular saws to chop saws, summer projects like deck builds and fence installations demand sharp, durable blades.

• Top picks: Carbide-tipped blades from DEWALT or Porter-Cable are popular for cutting through treated lumber with ease.

• When to replace: If your blade starts burning wood, binding, or producing rough cuts, it’s time for a replacement.

3. Trimmer Line and Heads

Yard work intensifies during summer, and that means frequent use of your string trimmer.

• Popular brands: Black & Decker and Makita trimmer heads and spools.

• Pro tip: Choose thicker, heavy-duty line (0.080" or more) for dense grass and weeds.

4. Drill Bits and Driver Sets

If your summer checklist includes assembling furniture, hanging outdoor fixtures, or working on small repairs, your drill will see action.

• In-demand parts: Impact-rated bits from Makita or DEWALT that can handle tougher jobs.

• Must-have feature: Magnetic tips and hex shanks for easy bit changes and better grip.

5. Carbon Brushes and Motors

Power tools that run frequently in hot weather—like sanders, grinders, or circular saws—can wear down internally. Carbon brushes are a small but essential part that keep motors running.

• Popular replacements: OEM brushes for Porter-Cable, Makita, and DEWALT models.

• Watch for signs: If your tool starts sparking or losing power, brushes might be worn out.
