1-1/2 x 15 in SDS Max Rotary Hammer Drill Bit - Tough Masonry Bit

Our review of the 1-1/2 x 15 in SDS Max Rotary Hammer Drill Bit focuses on practical performance for heavy masonry work. This review finds the bit best suited to contractors, masons, and serious DIYers who need a deep, large-diameter hole in concrete, brick, or stone; its single biggest reason to buy is the combination of a long 15 in overall length and a carbide tip designed to handle repeated drilling into dense materials without excessive wear. The SDS Max shank makes it compatible with rotary hammers that accept large-diameter bits and provides a secure engagement for demanding jobs.

Key Features

• 38mm (1-1/2 in) diameter: Large bore size lets users create wide holes for anchors and sleeves in one pass, reducing time on site.
• 380mm total length: The 15 in length gives a long reach for through-drilling thick walls or deep anchoring tasks.
• 260mm drilling depth: A 10 in effective drilling depth allows setting deep anchors and running sleeves well into masonry.
• SDS Max shank: The robust shank design provides secure bit retention and reliable impact transfer in SDS Max rotary hammers.
• Alloy steel body with carbide tip: The heavy-duty construction helps resist bending while the carbide tip improves cut life in abrasive materials.
• Built for masonry: Intended specifically for concrete, brick, stone, and cement wall work so users know the bit is purpose-made for those materials.

Who It's For

This bit is aimed at professionals and experienced DIYers who regularly drill large holes in concrete, brick, or stone and need the extra reach of a 15 in bit. It suits jobs like installing heavy-duty anchors, through-wall sleeves, or prepping masonry for structural fixings where a deep, wide hole is required.

It is not ideal for light, occasional household use or for drills that do not accept an SDS Max shank; hobbyists with small hammer drills or those needing smaller diameters should look for a different size or a standard SDS Plus option.

Pros & Cons

Pros

• Large 38mm diameter cuts allow fast installation of sizeable anchors and sleeves.
• Long 380mm length and 260mm drilling depth reach deep fixings without extensions.
• SDS Max shank ensures a secure fit and efficient impact transfer in compatible hammers.
• Carbide tip adds wear resistance and keeps drilling performance steady over repeated holes.

Cons

• Mixed customer feedback on tip strength suggests care is needed on extremely abrasive or reinforced concrete; occasional users may find longevity varies by material.
• Not compatible with smaller SDS Plus tools, so check tool shank size before purchase.
