Milwaukee 48-89-2305 – Frequently Asked Questions

1) Will a Milwaukee 48-89-2305 cobalt bit drill stainless steel and other hard metals?
Hard metals are what the cobalt Red Helix bit is built for, along with PVC and wood. The cobalt alloy is rated for up to 15X the life of a black oxide bit, which is the difference that matters when you are drilling work-hardening metal rather than mild steel.
2) What size hole does the Milwaukee 48-89-2305 drill bit make?
It cuts a 1/8 inch hole. That is the single size on the 48-89-2305; if you need a pilot for a larger fastener or a different diameter, you are ordering a different bit number in the Red Helix cobalt line.
3) Will the Milwaukee Red Helix cobalt bit slip in the chuck of a keyless drill?
The shank has a 3-flat Secure-Grip, which gives the chuck jaws flats to bite instead of a round shank that spins under torque. That is the feature that keeps a small 1/8 inch bit driving in hard metal rather than polishing itself in the chuck.
4) Does the Milwaukee 48-89-2305 need a center punch to keep from walking?
The 135 degree split point starts on its own without walking, so you can skip the punch on most work. On a slick curved or plated surface a punch mark still helps, but the split point is doing that job by design.
5) Do small 1/8 inch cobalt bits snap easily in metal?
Breakage on small diameters usually comes from chip packing and a thin core. The Red Helix bit addresses both: a variable helix flute clears chips fast so the bit is not binding in the hole, and an enhanced tapered web thickens the core behind the point where 1/8 inch bits normally fail.
6) Can I use a cobalt drill bit on wood and plastic, or is it metal only?
Not metal only. The 1/8 inch Red Helix cobalt bit is listed for hard metals, PVC and wood, so one bit covers a mixed punch list, drilling a pilot in a steel frame and then a plastic or wood trim piece without changing bits.
