Milwaukee 48-20-9040 – Frequently Asked Questions

1) What sizes does the Milwaukee POWER TIP carbide hammer drill bit come in?
Two sizes are offered: a 5/8 inch bit measuring 5/8 x 4 x 6 inches (model 48-20-9040) and a 3/4 inch bit at 3/4 x 4 inches (model 48-20-9045). On the 5/8 inch bit the numbers break down as 5/8 inch diameter, 4 inch usable flute length, and 6 inch overall length, so your maximum hole depth is governed by the 4 inch flute, not the overall length.
2) Will a 5/8 inch Milwaukee 48-20-9040 bit drill deep enough for a wedge anchor through a conduit strap?
The 48-20-9040 has 4 inches of usable flute, so 4 inches is the practical depth limit in concrete. That covers the embedment of typical 5/8 inch mechanical anchors used for strap, box, and equipment mounting. If your anchor calls for embedment past 4 inches, you need a longer bit.
3) Which Milwaukee bit size should I pick for mounting electrical boxes and anchors on a masonry wall?
Match the bit diameter to the anchor, not the fastener. For 5/8 inch anchors use the 48-20-9040; for 3/4 inch anchors use the 48-20-9045. Both carry the same 4 inch usable length, so the only working difference between them is hole diameter.
4) Can I use this Milwaukee carbide bit in a standard hammer drill, or does it need a rotary hammer?
The POWER TIP carbide bit is built for use with both hammer drills and rotary hammers on masonry work. It is not a wood or metal bit, it is intended for concrete, block, and brick.
5) What materials can the Milwaukee POWER TIP hammer drill bit drill into?
Concrete, block, brick, and other masonry substrates. The tip is carbide, which is what lets it hold an edge in those abrasive materials. Use a different bit for steel, tile, or wood.
6) What does Milwaukee's POWER TIP design actually do on a masonry bit?
It is the tip geometry, and its job is start accuracy: the bit bites and stays on your mark as the hammer action begins instead of walking across the face of the concrete. That matters most on layout work where a hole a quarter inch off puts a box or strap out of line.
