Best Diamond Blades for the Hilti DSH 700-X
The Hilti DSH 700-X is Hilti's mainstream 14-inch handheld gas cut-off saw — 68.7cc, 4.7 hp (3.5 kW), 24.7 lb, auto-choke, designed for wet or dry cutting. Heavier and pricier than the Stihl TS 420 or Husqvarna K 770, but built for Hilti's tool-warranty-and-service operating model that fleet contractors lean on. Blade fit is standard — 14-inch, 20mm or 1-inch arbor. Picks below cross-fit from the gas-saw competitor set.

If You're Cutting Asphalt or Green Concrete
Different substrate, different bond. These hard-bond blades fit the DSH 700-X but are built for soft, abrasive material — not cured slab.
Better — Reinforced Concrete / Pro Sweet Spot
VA 14-inch Premium Sparkie ($90-120). Taller 12mm segments and softer bond — self-dresses on rebar and resists glazing. Hilti fleet contractors typically run premium blades because tool-warranty service is the value prop, not blade-bargain hunting. Sparkie pairs naturally with the DSH 700-X spindle. See the 14-inch roundup for full specs.
Best — Production Cutting
Husqvarna Elite-Cut S85 ($140-180). Cross-brand pick (yes, fits the DSH 700-X — 20mm or 1-inch is universal). Optimized bond for 4,000+ PSI concrete and steady rebar. Dealer-only. Hilti also makes its own diamond blade line (P-MC, P-RC variants) sold through Hilti direct — worth getting a quote from your Hilti account rep if you're already on a Hilti fleet agreement.
Compatibility Gotchas
| Issue | What to Check |
|---|---|
| Arbor mismatch | DSH 700-X spindle accepts 20mm or 1". Most blades ship with 1" arbor + 20mm bushing — fits either way. |
| RPM over-spec | Hilti's DSH 700/900 operating instructions list a 5,100 RPM max arbor speed for the 14" saw (the 700-X shares this engine platform). Any 14" blade rated 5,500+ RPM is safe — confirm the print and your nameplate. |
| Bond / substrate mismatch | Hard bond for asphalt or green; medium for cured concrete; soft for rebar-heavy or hard aggregate. |
| Wet plumbing | DSH 700-X takes Hilti's water kit. Required for OSHA silica compliance on most concrete cuts. |
| Hilti fleet agreement | If you're on Hilti's Fleet Management program, OEM Hilti blades may be included in your monthly fee — check before buying aftermarket. |
Hilti's Own OEM Diamond Blades for the DSH 700-X
Hilti sells its own 14-inch diamond blade catalog under the P-MC (multi-cut / multi-purpose), P-RC (reinforced concrete), and P-AS (asphalt) families. Sold through Hilti direct (no Amazon, no big-box) — typically priced for the Hilti Fleet Management bundle. Listed for completeness alongside our editorial aftermarket picks.
| Blade | Model # | Best For | Price |
|---|---|---|---|
| Hilti P-MC (Multi-Cut) | — | Multi-purpose: cured concrete + occasional rebar + masonry. Hilti's mid-tier general-use blade. | $180-260 (via Hilti dealer) |
| Hilti P-RC (Reinforced Concrete) | — | Reinforced concrete with #4-#6+ rebar. Soft bond self-dresses on steel contact. | $220-300 |
| Hilti P-AS (Asphalt + Green Concrete) | — | Asphalt cutting + green concrete (1-48 hrs after pour). Hard bond. | $200-280 |
Hilti OEM trade-off: if you're on a Hilti Fleet Management agreement, blades may be included in your monthly fee — check before buying anything aftermarket. If you're paying out of pocket, Hilti OEM costs 50-100% more than equivalent aftermarket blades (VA Ultra Value at $69.99, Premium Sparkie at $174.30) and ships through dealer channels instead of Prime. For Hilti fleet contractors, OEM warranty + service is a real benefit. For one-saw users, the aftermarket picks above usually pencil out better.
Operator Hazards & Field Notes
Kickback geometry
Cut with the lower-front quadrant of the blade. Upper-front-quadrant contact or a pinched kerf drives the saw up and back toward you — the leading cause of cut-off-saw injury. Two hands, stable stance, relieve long kerfs so they don't close on the blade.
Cold-start (auto-choke flooding)
The DSH 700-X's auto-choke is a real advantage — until it over-primes on a cold start or a stalled-cut restart. If you get about four unsuccessful pulls, stop: pull the spark plug, dry it, and crank with the throttle open to clear the cylinder before reinstalling. Repeated yanking on a flooded engine burns out the starter cord, not your problem.
Fleet / OEM blades
If you're on a Hilti Fleet Management agreement, OEM Hilti blades (P-MC / P-RC) may already be included in your monthly fee — check before buying aftermarket. If not, cross-brand picks (VA, Husqvarna, MK) fit the same 20mm/1" spindle and typically cost less per blade.
Hand-arm vibration (HAVS) — the hazard nobody plans for
Handheld gas cut-off saws are among the highest-vibration tools on a jobsite, and sustained exposure causes Hand-Arm Vibration Syndrome (HAVS) — permanent nerve and circulation damage that first shows as numb, blanching fingers. The EU Physical Agents Directive sets a daily Exposure Action Value of 2.5 m/s² and an Exposure Limit Value of 5.0 m/s² (A(8) over 8 hours); US OSHA addresses it under the General Duty Clause. Hilti publishes declared vibration values and fits Active Vibration Reduction on the DSH-X line — but AVR reduces, not eliminates, exposure. Pull the DSH 700-X's declared handle-vibration figure from the Hilti tool sheet, run it through a HAVS calculator, and cap daily trigger time. A sharp, correctly-bonded blade vibrates far less than a glazed one.
Why Blade Choice Matters on the DSH 700-X
The DSH 700-X's spindle profile and power output determine which blade bond pairs well with which substrate. Wrong bond, wrong tool — even a premium blade glazes in minutes. Work through our Diamond Blade Buying Guide for the bond-substrate matrix and our RPM Guide for max-RPM cross-reference.
OSHA Table 1 silica protocol applies whenever this saw cuts concrete dry. Plumb wet or pair with an OSHA-rated vacuum. See our Silica Dust Safety Guide for crew protocol.

Frequently Asked Questions
What size blade does the Hilti DSH 700-X take? ▼
The DSH 700-X takes a 14-inch (350mm) blade. The DSH 900-X variant takes a 16-inch (400mm) blade. Verify your specific model before mounting.
What arbor size do DSH 700-X blades need? ▼
The spindle accepts 20mm or 25.4mm (1") arbors. Most professional 14-inch blades ship with a 1" arbor and include a 20mm bushing — both fit. Confirm the bushing is seated when mounting via 20mm.
How does the DSH 700-X compare to the Stihl TS 420? ▼
The TS 420 is lighter (21.5 lb vs 24.7 lb) and slightly less powerful (4.4 hp vs 4.7 hp). The DSH 700-X's value prop is Hilti's tool-warranty-and-service model — fleet contractors choose it for the support agreement, not the raw spec sheet. Blade picks cross-fit between the two.
Wet or dry cutting on the DSH 700-X? ▼
Both. Hilti sells a dedicated water-attachment kit. OSHA Table 1 silica protocol requires wet cutting or a 99%-efficient vacuum dust system for most concrete and masonry work — applies to the DSH 700-X same as any saw.
Should I buy Hilti's own diamond blades or aftermarket? ▼
If you're on a Hilti Fleet Management agreement, OEM blades may already be included in your monthly fee. If not, cross-brand picks (Virginia Abrasives, Husqvarna Elite-Cut, MK Diamond) typically cost less per blade for equivalent performance on the same DSH 700-X spindle.
Can I use a DSH 700-X blade on a Stihl TS 420? ▼
Yes — both take 14-inch blades with 20mm or 1-inch arbors. Blades are interchangeable across the major 14-inch handheld gas cut-off saws (DSH 700-X, TS 420, K 770, K 970) as long as bond matches substrate.
