Milwaukee RED HELIX Cobalt Drill Bit 48-89-2309

ULTIMATE HARD METAL PENETRATION

When your crew is staring down high-tensile alloys or 304 stainless steel, standard black oxide bits are just a line-item waste. The Milwaukee 48-89-2309 RED HELIX™ Cobalt bit is a masterclass in metallurgical engineering, designed for the industrial fleet manager who demands maximum uptime and a lower cost-per-hole. By utilizing a specialized Cobalt alloy, this bit manages the extreme thermal loads that cause standard twist bits to lose their temper, ensuring your team keeps moving through the toughest substrates in the shop or on the deck.

• / 15X Lifespan vs. Standard Bits: High-grade Cobalt alloy construction maintains a sharp edge under intense heat, significantly extending fleet ROI.
• / QUADEDGE TIP™ Technology: Features four unique cutting edges to disperse heat and decrease friction for faster material removal in work-hardened metals.
• / VARIABLE HELIX™ Geometry: Engineered with a 35° helix angle that transitions to 15° for aggressive chip ejection without clogging the flute.
• / 135° Split Point Precision: Eliminates bit walking and the need for a center punch, allowing for immediate penetration on curved surfaces or stainless tubing.
• / 3-Flat Secure-Grip™ Shank: Optimized for high-torque drilling to prevent rotational slippage within the chuck, protecting both the bit and the tool.
