Genuine DeWalt DT8119L‑QZ 19 mm Extreme HSS Bi‑Metal Holesaw – Deep‑Cut Accessory for Cutting Metal, Wood & Plastic
Description
The DeWalt DT8119L‑QZ is a 19 mm diameter bi‑metal holesaw from DeWalt’s “Extreme” line, designed for demanding drilling applications. It features:
Hardened HSS teeth with around 8 % cobalt which increases wear resistance and helps maintain sharpness under heavy load.
A “deep‑cut” style which gives greater cutting depth compared to standard holesaws, meaning you can cut through thicker materials in one pass.
Bi‑metal construction to combine toughness (for shock & heat) and flexibility (so the tool resists chipping or breaking under varied loads)
Useful plug removal slots (angled) to assist ejecting the cut-out material / “plug” more easily after cutting. This aids productivity.
It’s suitable for cutting holes in a wide range of materials including steel, stainless steel, aluminium, brass, copper, wood, plastic, plaster etc.
This holesaw isn’t specific to a single tool model; rather, it is a standard accessory that can be used with:
Any cordless or corded drill that accepts standard holesaws / has a compatible arbor/mandrel for 19 mm holesaws.
DeWalt’s own lineup of cordless drills/hammer drills or other brands, as long as your tool can take this kind of accessories.
