Virginia Abrasives 14-Inch BD Asphalt / Green Concrete Diamond Blade

The Virginia Abrasives 14-inch BD Asphalt / Green Concrete blade is the specialty pick for soft, abrasive substrates. Hard bond, 12mm segments, alternating drop segment geometry with U-slot gullets — designed to clear the sticky slurry that defeats standard concrete blades on asphalt and uncured concrete.

Who this blade is for

Road work crews, parking lot repair contractors, and any team cutting early-entry expansion joints or green concrete within 48 hours of pour. The hard bond is the engineering point — soft material wears segments fast, so you need a bond that resists premature wear. Standard concrete blades fail in minutes on asphalt because the medium bond exposes diamonds faster than the soft substrate can wear through them.

If your typical work is cured concrete, this isn’t your blade. The hard bond glazes on hard substrates because the diamonds don’t get exposed fast enough. The right blade for cured concrete is the Ultra Value (entry tier) or Premium Sparkie (pro tier).

Why hard bond on soft substrate

Diamond blade bond selection is counter-intuitive. The rule:

• Hard substrate → soft bond (so diamonds get exposed as the substrate wears the matrix)
• Soft substrate → hard bond (so the matrix doesn’t wear faster than the diamonds themselves)

Asphalt is soft and abrasive — exactly the substrate where you need the matrix to hold its diamonds tight while the substrate wears. The BD blade’s hard bond does that.

Cutting technique

For asphalt: wet cut whenever practical. Water cools the blade and flushes binder slurry. Set the saw to its rated RPM (around 5,350-5,400 on most 14-inch handhelds) and let the blade do the work — don’t force feed. Hot asphalt softens the binder; cold asphalt cuts cleaner.

For green concrete: timing is the variable. Early-entry saws cut 1-4 hours after pour with soft-cut blade geometry that minimizes raveling. Conventional 14-inch saws cut 4-12 hours after pour. Depth: 1/4 of slab thickness for expansion joints. Always wet-cut green concrete to avoid raveling and silica dust generation.

Saw fit

Same standard format as the rest of the VA 14-inch line — 1-inch arbor with 20mm bushing included. Fits every major 14-inch handheld cut-off saw and most 14-inch walk-behind concrete saws.

This blade is the right call for asphalt and green concrete work — and the WRONG call for cured concrete, which we say clearly on this page.
