ARTU Drill Bit, 5/16 in, Cobalt, 4-1/2 in, 2-5/8 in Depth, 118 Degree Tip, Individual

Drills cleanly through tough stock without the usual fuss.

Keeps the cut steady when the material gets stubborn.

Product Overview:

When a drill bit has to bite into hard material, you notice fast if it is up to the job. This ARTU drill bit handles rotary or percussion drilling with a calm, sure feel. It is built for hardened steel, tile, marble, plastic, cast metal, concrete, glass, plexiglass, granite, fiberglass, brick, masonry, PVC, and wood, so you are not hunting around for another bit every five minutes. The 118 degree tip helps it start true, and the no center punch design keeps walking in check. That saves time, saves nerves, and frankly, it just feels better in the hand.

Key Features:

• Cobalt and tungsten carbide tip: Built for hardness and heat resistance up to 2000 F, so it keeps its edge when the work gets rough.
• No center punch needed: Starts without wandering, which gives you a cleaner first touch and a steadier line to follow.
• Flat bottom parabolic flute: Clears waste faster, so the cut stays open and the drill does not feel bogged down.
• Chrome vanadium steel shank: Adds strength and a bit of give, a solid mix when you want the tool to hold up and keep its shape.
• Resharpenable design: You can bring it back on a silicon carbide grinding wheel, which makes good sense when you want more life from one bit.
• ANSI standard compliant: Made to line up with familiar expectations, so it sits well in a shop that likes things done right.
