All modern DeWalt cordless jigsaws use T-shank blades, which means any T-shank blade from any manufacturer fits your DeWalt jigsaw. You’re not limited to DeWalt-branded blades — Bosch, Makita, Milwaukee, and others will fit perfectly and often cost less.
The key decision is which blade to use based on what you’re cutting: tooth count, material composition, and design. This guide shows you what fits DeWalt, what works best, and where to find blades that give you the best results.
DeWalt Cordless Jigsaw Models & T-Shank Compatibility
| Model | Voltage | Platform | Blade Type | Notable Features |
|---|---|---|---|---|
| DCS331N | 18V XR | XR (Compact) | T-Shank | Compact, lightweight. Entry-level. |
| DCS334N | 18V XR | XR (Standard) | T-Shank | Full-size, more power. Best-seller. |
| DCS335N | 18V XR | XR (Premium) | T-Shank | Brushless, LED, orbital settings. |
| DCS330 (older) | 18V | Legacy | U-Shank | Discontinued. Used U-shank (not T-shank). |
Important note for older owners: The DeWalt DCS330 (the model before the DCS331) used U-shank blades, not T-shank. If you own a DCS330, you’ll need U-shank blades. These are becoming hard to find in the UK. If U-shank availability is an issue, upgrading to a DCS331N or DCS334N opens up access to the full range of modern T-shank blades.
All current DeWalt jigsaws (DCS331N, DCS334N, DCS335N, and all newer models) use T-shank.
Compatible Blade Brands for DeWalt Jigsaws
Because all modern DeWalt jigsaws use T-shank, the following brands fit perfectly:
- Bosch (T101B, T101A, T101BR, T118A, etc.) — best UK availability and value
- Makita (791303, 791304 series) — excellent quality, widely available
- Milwaukee (48-25 series) — premium blades, very durable
- DeWalt (DT series) — matched to your saw, good quality
- Ryobi (CSB series) — budget option, good for hobbyists
- Generic T-shank blades — check reviews; quality varies widely
Best Jigsaw Blades for DeWalt Jigsaws
Best All-Round Blade for General Wood Cutting
Bosch T101A — Bi-metal, 10 TPI. A versatile blade that handles general wood, plywood, and soft materials. It’s faster than fine-tooth blades but produces a cleaner finish than aggressive ones. The best single blade for all-purpose use.
Best for Rough Work & Demolition
Bosch T101B — High-carbon steel, 6 TPI. A fast, aggressive blade perfect for demolition, pallet busting, and construction work. Budget-friendly and readily available. It will dull quickly on hardwood but is inexpensive to replace.
Best for Laminate, Veneered Boards & Clean Cuts
Bosch T101BR — Bi-metal, 14 TPI, reverse-tooth design. The reverse teeth cut from both directions, preventing chip-out on kitchen worktops, veneered panels, and any high-visibility surface. Slower than standard blades but essential for quality finishes.
Best for Metal & Aluminium Cutting
Bosch T118A — High-speed steel (HSS), 24 TPI. A fine-tooth blade designed specifically for thin sheet metal, aluminium, and soft metals. Cuts slowly but produces a smooth, precise finish. Essential if you’re cutting metal regularly.
Best DeWalt-Branded Blade Set
DeWalt DT2299QZ — Five-blade T-shank assortment: general wood, fine wood, laminate, and metal. Good if you want to stick with the DeWalt brand, and it offers solid variety.

How to Choose the Right Blade for Your Job
| Task | Recommended Blade | Why |
|---|---|---|
| General wood (any size) | Bosch T101A (10 TPI) | Balanced speed and finish. Works on plywood, softwood, hardwood. |
| Rough demolition | Bosch T101B (6 TPI) | Fast, aggressive. Don’t care if it dulls — it’s cheap. |
| Kitchen worktops or visible finishes | Bosch T101BR (14 TPI, reverse) | Chip-free on both sides. Perfect for quality work. |
| Metal or thin sheet steel | Bosch T118A (24 TPI) | Fine teeth, designed for metal. Prevents binding. |
| Tight curves in thick wood | Bosch T101A (10 TPI) | Narrow blade for manoeuvrability, medium aggression. |
Key Points for DeWalt Jigsaw Owners
T-shank is universal: Any T-shank blade (Bosch, Makita, Milwaukee) will fit your DCS331N, DCS334N, or DCS335N perfectly. You don’t need to buy DeWalt-branded blades. Often, you’ll find better value and wider selection with Bosch.
Blade performance is determined by tooth count and material, not brand: Two T-shank blades from different manufacturers with the same TPI and material will cut identically. The choice of blade type (TPI, material, reverse-tooth vs. standard) matters far more than whether it says DeWalt, Bosch, or Makita.
Older DCS330 users need to know: The original DeWalt DCS330 used U-shank blades, not T-shank. All newer DeWalt models (DCS331, DCS334, DCS335) use T-shank. If you’re unsure, check your blade holder — one vertical slot means T-shank; two circular holes mean U-shank.
Build a blade inventory: Keep a variety on hand: one 6-TPI for demolition (T101B), one 10-TPI for general wood (T101A), one 14-TPI reverse for clean cuts (T101BR), and one 24-TPI for metal (T118A).

Frequently Asked Questions
Can I use Bosch T-shank blades in my DeWalt jigsaw?
Yes. All T-shank blades (Bosch, DeWalt, Makita, Milwaukee) fit all T-shank jigsaws. Bosch blades are often the cheapest and most widely stocked in the UK.
Is my older DeWalt jigsaw T-shank or U-shank?
Check the blade holder. One vertical slot = T-shank (modern DCS331, DCS334, DCS335). Two circular holes = U-shank (older DCS330 model). U-shank blades are hard to find now; consider upgrading to a T-shank model for better blade availability.
Do I need to buy DeWalt-branded blades for my DeWalt jigsaw?
No. DeWalt blades are no different in performance than equivalent Bosch, Makita, or Milwaukee blades of the same tooth count and material. You’ll often find better prices with Bosch.
What’s the difference between a 6-TPI and 14-TPI blade?
TPI = teeth per inch. A 6-TPI blade is aggressive and fast — good for demolition. A 14-TPI blade is slower and cleaner — good for finish work and laminate. Use the right TPI for your job.
Can I cut metal with a wood blade?
Not effectively. A wood blade (like T101A) will dull quickly on metal and produce poor results. Always use a metal blade with high TPI (like T118A) for thin metal and aluminium.
What does “reverse-tooth” mean?
Reverse-tooth blades have some teeth pointing backward. They cut on both the downstroke and upstroke, preventing chipping on the top and bottom surfaces. Essential for laminate, veneered panels, and visible cuts.
