1 / 3Bosch HC5091 1-1/2-in. x 21-in. SDS-Max Speed-X Carbide Rotary Hammer Bit
Bosch HC5091 is a 1-1/2-inch Speed-X carbide rotary hammer bit for concrete and masonry drilling. Its SDS-Max shank, solid carbide head and centering tip target larger-diameter holes, including precision anchoring applications, when used with a compatible hammer.
At a glance
- The SDS-Max shank is listed for SDS-Max-compatible rotary hammers. The listing also claims compatibility with Hilti hammers using TE-Y/TE-FY shanks.
- A solid carbide head and centering tip are presented for drilling masonry and concrete, including hard or reinforced concrete.
- Inclined side cutters are described as an aggressive cutting feature. Speed and longer sharpness are manufacturer claims, not independently verified results.

Pros and cons
Pros
- The 1.5-inch cutting diameter suits buyers who need a larger hole than a typical small-diameter masonry bit.
- The SDS-Max shank and claimed Hilti TE-Y/TE-FY compatibility broaden the listed hammer fit options.

What to know before buying
Listing details to confirm
The listing is inconsistent about overall length: the title and included-components entry say 21 inches, while a description calls the bit 16 inches by 21 inches. Confirm the actual bit dimensions before purchase. The finish is listed as Titanium without further explanation, and claims about compatibility, speed and longevity are not independently confirmed.

Who is it for?
A good fit for
- Tradespeople or experienced DIYers drilling larger holes in concrete or masonry with an SDS-Max rotary hammer.
- Buyers needing a centering tip for anchoring or other work where hole placement matters.
- Users whose Hilti hammer specifically accepts TE-Y/TE-FY shanks, subject to checking the tool manual and selected listing.
Less suited to
- Users with SDS-Plus or standard chuck-only drills, unless their tool supports the listed shank through a suitable compatible system.
- Buyers who need an unambiguous confirmed overall length without first resolving the listing's dimensional discrepancy.

Customer feedback reports positive experiences with quality, functionality and concrete drilling performance, with some customers describing effective work in hard sandstone and considering the bit worth the cost. Other feedback raises size concerns, while durability and speed impressions are mixed. For buyers choosing this bit by its listed 1.5-inch diameter and SDS-Max fit, size feedback makes confirming dimensions especially important. The listing's carbide and centering-tip claims provide product context but do not establish customer experience.
Positive themes

- Some customers say the bit is worth the money.
Negative themes
- Some customers express disappointment with the size.
Mixed feedback
- Customer impressions of durability and drilling speed vary.
