Description:
Featuring our signature Sawtooth Eccentric Geometry, this kit is engineered with a quad‑flute serrated twist bit profile to deliver ultra‑clean threading and rapid chip removal. Ideal for masonry drill bits for brick and concrete bits for drill, each flute channels debris away from the workpiece, minimizing clogging and heat build‑up on tough substrates.

Our TiN‑Coated Durability & Heat Resistance treatment deposits a titanium nitride film that strengthens the titanium film high‑temp resistant bit surface. You’ll experience extended bit life even under intense brick/stone drilling carbide tip conditions and frequent use on cement drill bit tasks.

Save time with Drill‑and‑Tap Combo Efficiency: the integrated high‑performance tap‑drill set design lets you drill and thread in one smooth pass. No tool changes, no extra attachments—perfect for contractor ceramic & stone projects and on‑site maintenance where speed matters.

Enjoy Multi‑Material Compatibility across universal metal/wood/plastic bit applications. Whether you’re working on steel panels, wooden frames, or PVC fittings, this cross‑material eccentric drill bit roster delivers consistent hole quality.

Built for Heavy‑Duty Masonry & Concrete Applications, the jobsite high‑strength twist drill geometry and carbide tips stand up to the rigors of professional construction and renovation. From overhead drilling in brick walls to anchoring in concrete footings, these bits resist breakage and maintain sharpness.

Our Assorted Diameter Selection (4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm) ensures you always have the right size on hand. The multi‑size high‑precision bits kit is perfect for electricians, plumbers, carpenters, and DIY enthusiasts who demand versatility without carrying bulky toolboxes.
