Milwaukee 48-20-9052 – Frequently Asked Questions
1) What sizes come in the Milwaukee 48-20-9052 SHOCKWAVE carbide hammer drill bit set?
The 7-piece Milwaukee SHOCKWAVE Impact Duty carbide set covers the common anchor sizes: one 5/32 in., two 3/16 in., two 1/4 in., one 5/16 in., and one 3/8 in. Every bit is 4 in. of flute with a 6 in. overall length, so you get the duplicates in the two sizes that burn up fastest on tapcon and anchor work.
2) Will these Milwaukee SHOCKWAVE bits fit an impact driver, or do I need a hammer drill?
Both. The bits use a 1/4 in. hex shank, so they drop straight into an impact driver chuck as well as a hammer drill's chuck, and Milwaukee builds the SHOCKWAVE Impact Duty line specifically for the hammer and impact duty cycle. That's the main difference from an SDS bit, which only works in a rotary hammer.
3) Can I drill into concrete block and brick with the Milwaukee 48-20-9052 set?
Yes, concrete, brick, and block are the rated materials for this carbide-tipped set. The carbide tip is precision ground for faster starts and the wide flutes clear masonry dust as you go. It is not a wood or metal twist bit set.
4) What is the difference between the Milwaukee SHOCKWAVE carbide set and a Relton carbide-tipped percussion bit?
The Milwaukee 48-20-9052 is a 7-piece set of SHOCKWAVE Impact Duty carbide hammer drill bits with a 1/4 in. hex shank, so they run in impact drivers as well as hammer drills, and they cover 5/32, 3/16, 1/4, 5/16 and 3/8 inch in concrete, brick and block. The Minerallac 59736 is a single Relton carbide-tipped rotary/percussion bit in 1/2 in. x 6 in. - one size, bought when you know the hole diameter, rather than a graduated set.
5) Can I use the Milwaukee 48-20-9052 bits to cut tile or stone the way a diamond grit bit does?
No - the Milwaukee 48-20-9052 SHOCKWAVE bits use a precision ground carbide tip intended for concrete, brick and block under hammer or impact action. Hard, brittle materials that call for abrasive cutting instead of percussion are the job of a diamond grit bit such as the Lenox 12111-10DGHS D/S-10Dg in 5/8 inch. Matching the cutting method to the material is what keeps the tip alive.
6) My crew only carries impact drivers on the ladder - which masonry bit works without hauling a hammer drill up?
The Milwaukee 48-20-9052 set is the one built for that: the bits have a 1/4 in. hex shank and are engineered for hammer drills and impacts, so a standard impact driver will run them for small anchor holes from 5/32 up to 3/8 inch. The Minerallac 59736 Relton 1/2 in. x 6 in. bit is a rotary/percussion bit, the pattern you would put in a drill rather than a hex-shank driver.
7) What is the Milwaukee part number for the 7-piece SHOCKWAVE carbide hammer bit set?
Order it as Milwaukee 48-20-9052. That single MPN covers the complete 7-piece Impact Duty carbide hammer drill bit set, 5/32 in. through 3/8 in.
8) Why do the bits keep walking when I start a hole in concrete, and does this set help?
Bit walk at the start usually comes from a dull or blunt tip skating on a hard surface. Milwaukee grinds sharpened carbide edges on the SHOCKWAVE tip for faster starts and less walking, and a chip breaker spreads the material load across the tip so the bit tracks more evenly once it bites.
