Milwaukee 48-89-4606 – Frequently Asked Questions

1) What sizes do the Milwaukee SHOCKWAVE Titanium RED HELIX drill bits come in?
Ten fractional sizes, each with its own Milwaukee part number: 9/64 in (48-89-4606), 5/32 in (48-89-4607), 3/16 in (48-89-4609), 13/64 in (48-89-4610), 7/32 in (48-89-4611), 5/16 in (48-89-4617), 11/32 in (48-89-4619), 25/64 in (48-89-4622), 7/16 in (48-89-4625) and 31/64 in (48-89-4628). Order by the part number for the size you need, since each is sold as its own bit.
2) Can I run a Milwaukee SHOCKWAVE titanium bit in an impact driver, or do I need a drill?
These are Impact Duty rated, built specifically for the concentrated torque and vibration an impact driver or impact-rated drill produces, where a standard twist bit can snap. They also run fine in a conventional drill. If you are working out of an impact driver all day, this is the line to use rather than plain uncoated HSS bits.
3) I need a 5/8 inch hole in tile or stone. Will one of the Milwaukee 48-89 SHOCKWAVE bits do it?
No, on two counts. The Milwaukee SHOCKWAVE Titanium RED HELIX line tops out at 31/64 inch (48-89-4628), so 5/8 inch is outside the size range, and the bits are titanium-coated twist bits for metal, wood, and plastic. For a 5/8 inch hole in hard, abrasive material, a diamond grit bit such as the Lenox 12111-10DGHS, a 5/8 inch D/S-10Dg diamond grit drill bit, is the type of tool built for that cut.
4) Which Milwaukee SHOCKWAVE bit do I order to tap 1/2-13 threads?
For a 1/2-13 UNC tap the standard tap drill is 27/64 in, which is not one of the ten sizes offered here; the closest available are 25/64 in (48-89-4622) and 7/16 in (48-89-4625). If you are drilling clearance holes for a 1/2 in bolt rather than tapping, 31/64 in (48-89-4628) or 1/2 in is what you want, and 31/64 in is stocked as 48-89-4628.
5) What is the difference between a SHOCKWAVE Titanium bit and a carbide-tipped rotary/percussion bit like the Relton 59736?
They cut different materials with different tool actions. The Milwaukee SHOCKWAVE Titanium RED HELIX bits are titanium-coated with a helical flute geometry that clears chips, and they are Impact Duty rated for the torque and vibration of impact drivers, drilling steel, wood, and plastic in sizes up to 31/64 inch. The Minerallac 59736 Relton bit is carbide-tipped and designated rotary/percussion, meaning it is fed by a hammering action for masonry, and it is a 1/2 inch by 6 inch bit. A crew doing both metal and concrete work on the same job carries both types rather than substituting one for the other.
6) What does RED HELIX actually do compared with a standard twist bit?
It is Milwaukee's flute geometry, shaped to pull chips away from the cutting edge faster. In practice that means less binding and less stalling in deeper holes, which matters most in metal where packed chips are what usually grabs the bit and twists it.
7) Is the titanium on these Milwaukee bits worth it, or is it just marketing?
The titanium coating on the bit body is there to resist heat buildup and wear, which is what extends life over an uncoated bit. Heat is what kills a bit drilling steel, so on metal work the coating earns its place. In wood it makes less difference.
8) Are these Milwaukee SHOCKWAVE bits sold individually or as a set?
Each size is its own item with its own Milwaukee part number and UPC, so you buy the single diameter you need rather than a kit. For example 25/64 in is 48-89-4622 and 13/64 in is 48-89-4610.
