Bosch Bulldog SDS+ 1/4" Hammer Bit

This Bosch HC2042 is a 1/4-inch SDS Plus hammer drill bit built for concrete and masonry work. Its four-flute geometry clears dust quickly and reduces heat buildup during extended drilling. The optimised brazing and hardening process extends service life in tough conditions. Tradespeople and DIY users gain a reliable bit for anchor and fastener holes.

Suited for SDS+ rotary hammers only

The SDS Plus shank fits compatible rotary hammers and will not work in standard three-jaw chucks or SDS Max machines. Buyers needing a smooth-shank bit for a drill driver should choose a different style. Those requiring larger diameters or longer reach must select another bit. This item serves the 1/4-inch hole size exclusively.

Single specification: 1/4-inch SDS Plus shank

The 1/4-inch SDS Plus shank is the decisive specification that determines tool compatibility. If your rotary hammer accepts SDS Plus, this bit will engage securely. If your tool uses a different chuck system, the bit cannot be used. Verify the shank type before purchase.

Questions about this item

Does the HC2042 come with any extra accessories or do I need to buy a separate SDS Plus chuck?

The bit is sold as a single unit and fits directly into any SDS Plus rotary hammer; no additional chuck or accessory is included in the box.

How do I decide between the 1/4 inch x 6 inch and 1/4 inch x 8 inch versions of this bit?

The 6 inch length suits shallow anchor holes and tighter workspaces, while the 8 inch length reaches deeper embedments and thicker materials.

What does the four-flute design actually do when the bit is spinning in concrete?

Four cutting channels evacuate dust faster, reduce friction heat and spread load across more carbide edges, so the bit stays sharper longer.
