Stone Chisels: Choose Type and Shank | Saniso

Stone chisels: which type and shank do you need?

A stone chisel cuts, breaks or marks masonry and hard building materials: by hand with a hammer on a flat chisel, or in a rotary hammer or breaker with a HEX or SDS shank.

At Saniso the STALCO and STALCO PERFECT lines cover thirty-one stone articles: flat chisels (hand / hammer), HEX chisels, SDS-max chisels and SDS-plus chisels, plus the parent range chisels for concrete and stone. Saniso B.V. in Zwaag sells the STALCO / STALCO PERFECT brand as a wholesaler and webshop.

What is a stone chisel (for concrete and masonry)?

It is a cutting or breaking tool for stone, concrete, brick and similar hard materials — not a wood chisel for carpentry. On Saniso this guide covers hand flat chisels (hammer-type) and machine chisels with Hth HEX 30, SDS-max or SDS-plus shanks. Choice here is mainly shank / drive and blade form (pointed, narrow, wide, spade, hollow or set).

Why use a stone chisel for masonry, concrete and demolition?

You use a stone chisel for masonry, concrete and demolition when you need to break out material, open channels, remove plaster or tiles, or mark slots for wiring and pipes. Flat STALCO pages (for example S-20500 and wide-head S-20506) describe renovation work such as removing plaster, tile coatings or old adhesive. SDS and HEX pages name breaking concrete and stone, demolition chiselling, and — for the hollow SDS-max S060572357 — clean channels and chases for electricians, installers and plumbers. The HEX 30 spade S060572361 is aimed primarily at road work when removing asphalt.

Who typically uses these chisels?

Masons, demolition crews, renovators, electricians and installers who work stone or concrete by hand or with a rotary hammer / breaker — matching how the STALCO and STALCO PERFECT product pages describe renovation, construction and trade use. This guide stays on stone chisels only (thirty-one articles).

Shank types: flat hand, HEX 30, SDS-max and SDS-plus

Match the chisel to how you drive it. Flat, HEX and SDS are not interchangeable.

• Flat / hand (hammer-type): struck with a hammer; no machine shank. Six articles under flat chisels — STALCO lengths 250 / 300 / 350 × 25 mm plus wide heads, and STALCO PERFECT S-69512 / S-69516.
• HEX 30: hexagonal shank for HEX-compatible breakers. Four STALCO PERFECT shapes: pointed (S060571629), narrow, wide and spade.
• SDS-max: for rotary hammers / demolition hammers with an SDS-max chuck. Fourteen articles on the SDS-max chisels leaf (plus two further SDS-max STALCO concrete chisels available on their product pages). Example entry pointed: S-26601; narrow renovation: S-71616 (product page: rotary hammers 5–12 kg).
• SDS-plus: for lighter SDS-plus impact drills and hammers. On the SDS-plus chisels leaf: set S-28225, self-sharpening S-71625 and S-71626, and two self-sharpening articles whose titles state SDS max — S-71627 and S-71628 — while they sit on the SDS-plus leaf.

Machine HEX and SDS articles also appear under the parent chisels for concrete and stone. Flat chisels sit under hammer-type tools → flat chisels.

Blade forms: pointed, narrow, wide, spade and sets

Several STALCO PERFECT SDS and HEX titles also state self-sharpening where that wording appears on the product page.

Which type fits which job

First choose the chisel type from the shank in the title (hand, HEX 30, SDS-max or SDS-plus). Then choose the blade form.

What these STALCO stone chisels have in common

Across the STALCO and STALCO PERFECT stone-chisel pages in this assortment (only where the own product page states it):

• Hardened carbon steel (flat STALCO) or chrome-vanadium (CrV) tip (flat STALCO PERFECT)
• Handle with hand-protecting shield / collar on flat models; bi-material handle on PERFECT flat
• Alloy / high-quality steel wording on many SDS and HEX pages
• Self-sharpening tip where the title or features say so
• Applications named for concrete, stone, brick (and asphalt / soil on the HEX spade)
• Set S-28225: three SDS-plus accessories for renovation and demolition

Feature wording is not identical on every article — check the live page for the code you buy. Marketing phrases such as “long service life” or “excellent price-to-performance” stay on the product page; they are not treated here as measured lab facts.

Frequently asked questions

How do you choose between flat, HEX, SDS-max and SDS-plus chisels?

Start from your drive: hand + hammer → flat chisels; HEX-compatible breaker → HEX 30; rotary hammer / demolition hammer with SDS-max chuck → SDS-max; lighter SDS-plus machine → SDS-plus. The shanks are not interchangeable — match the chuck on the tool.

When do you need a pointed chisel versus a wide or narrow one?

A pointed tip concentrates force for breaking hard material. A narrow blade suits channels and more precise chiselling. A wide or wide-head blade removes more surface (plaster, tiles, broader faces). A spade HEX 30 is for asphalt / road-style removal on that product page; a hollow blade is for clean channels and chases.

Which shank fits which rotary hammer or breaker?

Read the shank in the product title: HEX 30, SDS-max or SDS-plus. Your machine’s chuck must match. Example: S-71616 names rotary hammers in the 5–12 kg class on its page. Flat chisels have no machine shank — you strike them with a hammer.

Do you need a concrete chisel set or single sizes?

A set helps when you want starter coverage without picking every form first — S-28225 is a three-piece SDS-plus concrete chisel set (two flat-ended + pointed). Choose a single when you already know the shank and blade form (pointed, narrow, wide, spade or hollow).

What is the difference between a stone chisel and a wood chisel?

A stone chisel (this guide) is for masonry, concrete and hard building materials — hand flat or machine HEX/SDS. A wood chisel is for carpentry and woodworking and is a separate assortment. Keep wood and stone tools in separate categories when you order.
