Three Shapes. One Set. Every Stubborn Surface – Conquered.

OSCARBIDE 3-Piece Carbide Scraper Blades Set – Round, Drop, and Triangle Shapes. Solid tungsten carbide. Removes paint, glue, varnish, and rust.

The Problem

You‘re spending hours scraping away stubborn paint, dried glue, or rust. Your steel scraper blades dull after just a few passes — or worse, they scratch and gouge the surface beneath. You’ve tried chemicals (messy, toxic, time-consuming), heat guns (risk of fire, damaged wood, blistered paint), and sanding (dusty, slow, wears out paper fast). There has to be a better way.

The Solution – OSCARBIDE Carbide Scraper Blades

Tungsten Carbide Construction – A solid tungsten carbide blade stays sharp up to 50 times longer than conventional steel scraper blades-2. No more constant blade changes mid-project. No more frustration.

3 Precision Shapes in 1 Set – One set gives you three blade profiles for every scraping challenge: triangular for corners and crevices, drop-shaped for flat surfaces and precision work, and round for curves and concave details. Why buy three separate packs when one set does it all?

10× Harder Than Steel – Tungsten carbide is approximately 10 times harder than hardened steel. That means it powers through dried glue, multiple layers of paint, and heavy rust without chipping or deforming.

Convex-Ground Edges – Blades feature precision-polished, convex-ground edges that reduce the risk of scratching your workpiece and cut smoothly on both push and pull strokes

25° Bevel Cutting Edge – Each blade is precision-ground to a 25° bevel, providing the optimal balance of sharpness and edge retention for scraping applications

These blades power through virtually any surface coating or residue:

1.Q: Which scrapers are compatible with these blades?

A: These blades are designed to fit scrapers with a 5.5mm mounting hole diameter and 1.5mm thickness – the industry standard for replaceable-tip carbide scrapers. They are directly compatible with:

Bahco 625 series scrapers (including 625 ERGO, 625-ROUND, 625-DROP compatible models

Bahco 449 25mm triangular blade scrapers

Most generic hand-held scrapers with removable blade posts

Not sure if your scraper is compatible? Remove your existing blade and measure:

Mounting hole diameter should be approximately 5.5mm

Blade thickness should be approximately 1.5mm

If your scraper uses a different system (e.g., 2-screw mounting, different hole size), these blades will not fit.

2..Q: How long does a carbide blade last compared to steel?

A: Tungsten carbide stays sharp up to 50 times longer than conventional steel scraper blades. Where a steel blade might dull after scraping a single door, these carbide blades will power through an entire house worth of paint stripping and still stay sharp. The material is also approximately 10× harder than hardened steel , making it resistant to chipping and deformation when scraping rough surfaces like concrete or metal.

3.Q: Which blade shape should I use for my project?

A: Here‘s a quick reference guide:

TRIANGLE Blade – Best for: Window frames, door jambs, baseboard corners, stair risers, cabinet corners, narrow crevices, and any tight angle-1. The sharp point reaches where other blades can‘t.

DROP Blade – Best for: Flat surfaces (walls, tabletops, floors), trim work, moldings, furniture stripping, and general-purpose scraping. The teardrop shape provides excellent control on broad surfaces.

ROUND Blade – Best for: Curved surfaces, chair rails, crown molding, concave profiles, rounded edges, and detailed restoration work. The circular shape follows contours without gouging.

Pro tip : For complex projects (e.g., a detailed door), use all three blades. Triangle for corners, round for curved panels, drop for flat stiles and rails. One set = complete coverage.

4.Q: Does carbide scratch surfaces?

A: These blades feature convex-ground edges specifically engineered to reduce the risk of scratching surfaces. The rounded profile glides over the workpiece without digging in. However, proper technique is essential:

Always scrape at a low angle (10–20°)

Let the blade‘s sharpness do the work — don‘t force it

On soft materials (softwood, plaster), use lighter pressure

Always test on an inconspicuous area first

5.Q: Can I use these blades for push and pull strokes?

A: Yes. The convex-ground design allows the blade to cut effectively on both push and pull strokes . This is a significant advantage over cheaper blades that only cut in one direction. You can scrape in whichever motion feels most comfortable and efficient for the task.

6.Q: How do I maintain these carbide blades?

A: Minimal maintenance required:

After each use: Wipe off any residue with a rag. Dried glue or paint buildup can affect performance.

Storage: Keep blades in the included plastic case to protect the sharp edges.

When the edge dulls: While carbide stays sharp much longer than steel, it will eventually dull. All three blades have 3 cutting edges – simply rotate the blade to a fresh edge if your scraper supports multi-position mounting, or replace when fully worn.

7.Q: Are these blades safe to use on glass surfaces (e.g., windows)?

A: Yes. These carbide blades are excellent for removing paint overspray, decals, tape residue, and dried adhesive from glass windows. However, exercise caution:

Use a shallow angle (5–10°) to avoid scoring the glass

Ensure the glass is clean of grit before scraping

Do not use on cracked or damaged glass

For extremely delicate glass (antiques), consider professional guidance

8.Q: My scraper uses a different mounting system. Can I modify these blades?

A: We do not recommend modifying the blades. They are made of solid tungsten carbide – extremely hard and brittle. Attempting to drill or grind the blades will likely crack or shatter them. If these blades don‘t fit your current scraper, consider purchasing a Bahco 625 series scraper handle (inexpensive and widely available), which is designed specifically for this blade format.

9.Q: Do these blades work on wet paint or only dry?

A: These blades are designed for dry removal of cured paint, varnish, glue, and rust. For wet paint, use a standard paint scraper. These carbide blades excel at removing fully dried, hardened coatings that steel blades struggle with.

10.Q: Are replacement screws included for the mounting hole?

A: The 5.5mm mounting hole is a standard pass-through design used by most carbide scrapers (e.g., Bahco 625 series). The scraper handle‘s post passes through the hole and is secured by a screw or nut on the opposite side. No additional screws are included. Use the mounting hardware that came with your scraper handle.
