Essential Power Tools Reference
Why this matters
Modern service trades depend on cordless power tools. The right battery platform + the right tool selection covers 95% of field work. Wrong tool = manual labor + slower job + tired tech. The shop with the right power tool stack works faster, safer, more profitably. This is the field card.
Battery platforms (pick one)
Milwaukee M18 / M12: best HVAC + plumbing-tool selection (cordless drain machines, pipe cutters, sectional cleaners).
DeWalt 20V Max / 60V FlexVolt: strong general construction; great cordless saw + drill range.
Makita 18V LXT / 40V Max XGT: smooth motors; large selection.
Bosch 18V: European quality; smaller selection in U.S.
Ridgid 18V: lifetime battery warranty; mid-tier; Home Depot exclusive.
Pick ONE platform: batteries are 50%+ of total cost; cross-platform = duplicate investments.
Drill / driver (every tech)
Cordless drill 1/2" chuck: 18 - 20V; 600 - 1,500 in-lb torque. Daily use.
Hammer drill function: percussive impact for masonry up to ~1/2".
Impact driver 1/4" hex: drives screws fast; concrete screws; fast removal.
Right-angle drill (Milwaukee Hole Hawg): between studs, joist drilling.
Rotary hammer SDS-Plus: serious concrete work; 3 - 6 J impact.
Cutting tools
Circular saw 7-1/4": lumber, sheet goods. Cordless OR corded.
Cordless 6-1/2" track saw OR mini circular: small material + precision.
Reciprocating saw (Sawzall): demo, plumbing, electrical access cuts. Cordless dominant.
Jigsaw: curves + small cuts.
Multi-tool (oscillating): flush cuts, sanding, scraping, grout removal. Surprisingly versatile.
Angle grinder 4-1/2": cutting, grinding, polishing. Metal + masonry + tile.
Miter saw 10" OR 12": angle cuts, lumber + trim. Bench tool.
Band saw (portable): pipe, electrical cable raceway, deep cuts.
Cordless chain saw: branch removal, light tree work, framing demo (rare).
Specialty cordless
Cordless sectional drain machine (Milwaukee, Ridgid): 50 ft sectional snake; battery-powered. Saves backache.
Cordless press tool (Milwaukee M18 Force Logic, Ridgid RP340): PEX + copper press-fit. Replaces solder + crimp for many jobs. A pricier specialty tool but pays back in productivity.
Cordless pipe cutter (Milwaukee M12 1-1/4"): clean cut PVC + copper.
Cordless impact wrench (1/2" + 3/8"): heavy fastener removal; HVAC blower install, vehicle work.
Cordless die grinder + cut-off tool: tight space metal cutting.
Cordless heat gun: heat shrink, removing paint, thawing pipes.
Cordless vacuum (Milwaukee, DeWalt): jobsite cleanup. Wet/dry small.
Cordless work light (multi-position LED): critical visibility.
Saws by trade
HVAC: reciprocating (sheet metal); tubing cutter for refrigerant lines (not powered); cordless cut-off for ductwork. Plumbing: reciprocating (PVC + cast iron demo); cordless press (PEX-A + copper); cordless drain machine. Electrical: reciprocating (cable channels, demo); drill + hole saws (panel openings); cordless impact (cable pulling, structural). Carpentry: circular, miter, jigsaw, multi-tool. Tile/flooring: wet tile saw (corded); angle grinder + diamond blade; multi-tool + grout-removal blade.
Compressors + pneumatic
Pancake compressor (1 - 2 gal): portable; pneumatic nailers (brad, finish, framing). Cordless air compressor (Milwaukee, DeWalt): tire inflate + small tasks. Pneumatic nailers: brad (18 ga) trim/light work; finish (15 - 16 ga) trim/crown; framing (8d - 16d) walls/deck. Cordless framing nailer heavy + expensive; corded preferred unless mobility critical.
Larger / less-common + storage
Concrete saw (corded OR gas): large concrete cuts. Table saw, bandsaw, wood lathe: bench/shop tools. Polishers/buffers: detail work. Storage: Packout/TStak/MakPac/TackleBox modular cases; truck shelving organized + accessible; cordless bag (drill, impact, recip) always with you.
Battery management
Number of batteries: 4 - 8 minimum (charge while using). Most platforms charge in 30 - 60 min.
Slim batteries vs heavy-duty: slim (3 - 5 Ah) for handheld; heavy-duty (9 - 12 Ah) for high-current (saws, vacuum, impact).
Rotate batteries evenly; don't deplete one all the time.
Charge in fanned environment: cool batteries last longer.
Replace at 200 - 500 charge cycles depending on platform + usage.
Cordless vs corded
Cordless wins: convenience, no cord drag, faster setup.
Corded wins: continuous high-current (vacuum, large saw, table saw, miter saw stand).
Best for service: cordless for handheld; corded for bench/long-run + heavy-duty.
Quality tiers
Pro brands (Milwaukee, DeWalt, Makita, Bosch, Ridgid, Hilti): a real per-tool investment; lifetime; service network; replacement parts available.
Consumer brands (Ryobi, Black + Decker, Skil, Porter Cable, some Craftsman): a fraction of pro-brand pricing; not built for daily pro use.
Avoid for service work: cordless from generic Amazon brands; failures + no parts.
Common power tool mistakes
Wrong tool for job (using drill as impact = strips fasteners). Skipping safety features (clutch on drill, kickback guard on saw). Working with damaged tool (electrical hazard). Wrong speed for material. Letting batteries die completely (LiPO + LiFe degrade if deep-discharged). Cheap tool that fails on warranty job. Tool not charged on arrival.
Maintenance
Lubrication: per manufacturer (impact drivers, drills have lubrication points).
Brushes: replace when worn (brushed motors only; brushless = no brushes).
Cooling vents: keep clear of dust.
Tool cleaning: blow out dust monthly with compressed air.
Battery contacts: clean periodically with brass brush.
OSHA safety
PPE: safety glasses always; hearing protection for circular saws + grinders.
Guards: never remove blade guards.
Tool inspection: cracked housing, damaged cord, missing guards = don't use.
One-hand vs two-hand operation: use both hands per manufacturer.
Common service-trade kit (starter)
Universal: drill 1/2" + impact driver + reciprocating saw + multimeter + work light + 4 batteries.
Add for trade:
- HVAC: cordless press tool, manifold, vacuum pump
- Plumbing: cordless press, sectional drain, propress jaws
- Electrical: impact wrench, hole saws, fish tape
- Carpentry / general: circular saw, miter saw
The single most-impactful power-tool habit is the SINGLE BATTERY PLATFORM commitment. Choose one platform (Milwaukee M18, DeWalt 20V, Makita 18V, etc.) + buy ONLY tools that share batteries. The bare tool is often the cheaper half of the purchase; the battery pack costs nearly as much as the tool itself, sometimes more. Buying a cheaper off-brand drill for the up-front bargain means owning ANOTHER battery type + ANOTHER charger + ANOTHER set of batteries. The cost of cross-platform = 3x more total spending. Pick one platform when you start + stick with it. Same for the next tech you hire.
