A Porter-Cable drill bit set is a sensible budget-to-midrange choice for home projects. The brand’s sets typically mix black oxide or titanium-coated twist bits with screwdriver bits, and they handle wood, plastic and mild steel well. They are not the right pick for stainless steel or heavy daily trade use, where cobalt bits from a pro-focused line last much longer. The key is buying the set whose bit material and size spread match the work you actually do, not the biggest piece count.

What we cover
Where Porter-Cable fits in 2026
Porter-Cable is part of Stanley Black & Decker, the same group as DeWalt and Craftsman. Over recent years the brand has narrowed its retail presence and focuses on homeowner and serious-DIY tools and accessories, sitting below DeWalt in price. Its accessory sets are mostly sold as general-purpose kits rather than specialized professional lines. Exact set contents and piece counts change between production runs, so it is more useful to understand set types than to chase a single SKU.
Bit materials you will see in Porter-Cable and similar sets
| Bit type | Relative hardness / heat tolerance | Good for | Not good for | Relative life in mild steel |
|---|---|---|---|---|
| Black oxide HSS | Baseline | Wood, plastic, aluminum, light mild steel | Stainless, hardened steel | 1x (reference) |
| Titanium nitride-coated HSS | Harder surface; coating wears off at the tip after sharpening | Mild steel, wood, general use | Stainless, regrinding (loses coating) | Roughly 1.5-3x |
| Cobalt (M35/M42 HSS) | Hardness through the whole bit; high heat tolerance | Stainless, hard steel, cast iron | Budget-only buyers; brittle if side-loaded | Roughly 3-5x+ |
| Brad point | Similar to HSS | Clean, accurate holes in wood | Metal | Not applicable |
| Spade / paddle | Carbon or HSS steel | Fast rough holes 3/8-1-1/2 in in wood | Clean-finish holes, metal | Not applicable |
Life multipliers are typical industry ranges and depend heavily on speed, feed and cooling. A cheap bit run at the right speed will outlast an expensive bit run too fast.
What size spread a set should have
Most general-purpose sets fall into a few patterns:
| Set style | Typical piece count | Typical twist bit range | Best for |
|---|---|---|---|
| Small twist-only set | 13-21 pieces | 1/16 to 3/8 or 1/2 in, in 1/64 or 1/32 steps | Pilot holes, hardware, light metal |
| Drill and drive combo set | 30-100+ pieces | 1/16 to 1/4 or 3/8 in, plus driver bits and nut drivers | Home toolbox, general repairs |
| Mixed material set | 15-40 pieces | Twist, masonry, spade and sometimes brad point bits | Homeowners who drill brick, wood and metal occasionally |
The most-used twist bit sizes in a home shop are 1/8, 5/32, 3/16 and 1/4 inch, since they cover pilot holes for common #6-#12 wood screws and clearance holes for 1/4-inch bolts. Check that a set includes those, and ideally duplicates of the smallest sizes, which break most often.
Drill-and-drive sets vs. the drill and impact combo kit
People searching for a “Porter-Cable drill and impact set” often mean one of two different things:
- An accessory set designed for both a drill and an impact driver, with hex-shank drill bits and impact-rated driver bits. Look for 1/4-inch hex shanks on the drill bits and “impact” labeling on the driver bits; standard screwdriver bits snap quickly in an impact driver.
- A tool combo kit, such as Porter-Cable’s 20V MAX drill/driver and impact driver kits (the PCCK604L2 is a long-running example). These include the two tools, batteries and a charger, and sit in a budget-to-midrange price bracket. They suit home use well; trade users usually move up to brushless pro lines.
Matching a set to your work
| Your typical jobs | Pick |
|---|---|
| Assembling furniture, hanging shelves, general repairs | Drill and drive combo set with titanium or black oxide bits |
| Woodworking with visible holes | Add a separate brad point set; twist bits tear out wood fibers |
| Brackets, angle iron, trailer repairs in mild steel | Titanium-coated twist set, 1/16-1/2 in |
| Stainless steel hardware or appliances | Cobalt set from any reputable brand |
| Occasional brick or block anchors | Mixed material set, or a separate carbide-tipped masonry set |
Speeds that make any set last longer
Bit life depends far more on RPM than on brand. A common starting point for HSS bits in mild steel is about 1,000 to 1,500 RPM for a 1/8-inch bit, around 600 to 800 RPM for 1/4 inch, and about 300 to 400 RPM for 1/2 inch, with cutting oil. In wood you can roughly double those speeds. Most cordless drills run around 400-600 RPM in low gear and 1,500-2,000 in high gear, so use low gear for larger bits in metal.
- Drill a small pilot hole first for anything over 1/4 inch in steel.
- Use steady pressure so the bit cuts a continuous chip; light pressure just rubs and overheats the edge.
- Back out to clear chips on deep holes.
Durability realities
- Small bits break first. 1/16 and 5/64 inch bits snap from side loads. Buy replacements in packs.
- Coatings wear. Titanium coating wears off the tip with use; once it is gone, performance drops to plain HSS.
- Cases matter. A case that holds each bit in a labeled slot saves time and stops bits chipping against each other.
- Driver bits are consumables. Phillips #2 bits wear fastest; impact-rated bits last much longer under an impact driver.
Price expectations
General-purpose Porter-Cable accessory sets usually sit in the roughly $15-$50 range depending on piece count and coating, with combo tool kits costing in the low hundreds. Cobalt sets from any brand cost more per bit but are the cheaper option per hole in hard metals.
Bottom line
A Porter-Cable drill bit set is a fair-value choice for home use, especially a drill-and-drive combo set that covers 1/16 to 1/4 inch twist bits plus common driver bits. Add a brad point set for fine woodwork and a cobalt set if you drill stainless. Run the bits at sensible speeds and they will last far longer than the piece count on the box suggests.
