COMMONLY USED ACRONYMS

Term	Meaning
Anti-kick or AKB	Anti-kickback — safety device on power tool accessories to help prevent grabbing and kickback of the work piece
ATB	Alternating Top Bevel — saw blade tooth profile
ATBR	Alternating Top Bevel with Raker — saw blade tooth profile
C1, C2, C3, C4, C6	Carbide tooth hardness grade — higher number = harder, longer-lasting, but more brittle
DKO	Diamond knock-out — type of saw blade arbor
DIY	Do-it-yourself
HCS	High carbon steel — softer steel suited to wood cutting only
Hook Angle	Tooth angle: high = faster/more aggressive; low/negative = smoother/less aggressive
RPM	Revolutions per minute
PCD	Poly‑crystalline diamond
Segmented, Turbo, Continuous	Diamond blade cutting configurations
SDS	Slotted drive system/shaft — tool retention system for rotary hammer drills
Shank	Shaft/stem of a power tool accessory that attaches to the tool
TCG	Triple chip grind — saw blade tooth profile
Tooth Grade	Tooth hardness — see C1, C2, C3, C4, C6
U Shank	Universal jigsaw blade shank — fits most jigsaws
T Shank	T‑shank jigsaw blade — common on Bosch and many modern jigsaws

EAB COMMONLY USED SYMBOLS

Icon	Meaning
General Quality	Designed for light and medium‑duty work including DIY projects. C2 grade tungsten carbide teeth; great value.
Professional Quality	For heavy‑duty needs. High‑grade carbide, precision grinding (top, sides, face). Hardened plates and thinner kerfs for finer results and less tool wear.
Industrial Quality	Top tier for extreme‑duty. Finest hardened steel with fully ground C4/C6 carbide; maximum life and minimal equipment wear.
	Indicates testing in our North American lab for quality, strength, and durability.
	Dollar value shows the credit applied to your next EAB purchase when you return the used accessory. See how to exchange.
	Reminder that most EAB products are recyclable.
	All steel blade with no carbide tips.

BLADE TYPE COLOR CODES

A quick guide to selecting the right blade for you and your job

Icon	Description
	Green Blades Value choice for many jobs; an ideal introduction to the green exchange system. Available for framing and finishing; made without chromium and with recycled carbide content.
	Decking & Framing GEN/PRO blades for ripping and crosscutting dimensional lumber and composites. Tough ATB teeth for clean, fast cuts.
	RAZOR BACK^® Heavy‑duty accuracy under high heat. Embedded sock tooth design minimizes tooth loss; anti‑kickback shoulder reduces grabbing; fine edge for fast, smooth cutting.
	All Purpose (Planer Combination) ATBR (4&1) tooth configuration for fast ripping and semi‑smooth crosscuts across wood types — a must‑have for contractors and DIYers.
	Miter‑Wood GEN chop‑saw blade for quick miter work; PRO/IND options for ultra‑smooth finishes on miter and radial arm saws with higher‑grade carbide.
	Finishing (Shelving & Cabinetry) GEN/PRO blades for softwoods & hardwoods where smooth finishes are required. PRO recommended for splinter‑free cuts on molding, paneling, veneers, and fine hardwoods.
	Ultra Thin Extra narrow kerf for faster, smoother cuts and minimal waste; ideal on veneers, paneling, fine hardwoods, and cordless/low‑power saws.
	Melamine/Laminates Extra‑fine finishing with TCG teeth and C3/C4 carbide; splinter‑free cuts in melamine, laminates, and hard plastics.
	Fiber Cement Designed for HardiePlank®, Cemplank®, and other fiber cement with minimal dust. IND blades feature long‑lasting PCD teeth.
	Miter‑Aluminum For non‑ferrous metals (aluminum, copper, brass). C6 carbide, TCG teeth, and −5° hook for fast, smooth, safe cutting.
	Metal Heavy/extreme‑duty blades for mild steel roofing, siding, and ≤ .062 gauge studs. Hardened plates, thin kerfs, chip‑limiting shoulders, and 0° hook reduce jams and overheating.
	RAZORTOOTH^® Ultimate finishing blades in PRO (C3) and IND (C4) for ultra‑smooth, mirror finishes on fine woods, veneers, and laminate flooring.
	LASERLINE^® Precision 10″ blades with C4 tips, laser‑cut plates, and anti‑noise/vibration vents for all purpose, melamine, miter‑wood, and miter‑aluminum cutting.
