Hollow SDS-Max drill bit designed to remove dust through its internal channel when used with a compatible dust-extraction system. The hollow design helps reduce airborne dust during drilling, can speed hole making, and aids adhesive-anchor installation. A Y‑cutter carbide tip provides precise positioning and durability for starting holes. The shank fits SDS-Max rotary hammers and the bit can form a secure, locking connection with dust-extractor systems that use an airlock-style interface. When used with an appropriate extractor and dust shroud, the system can meet OSHA Table 1 silica-control requirements.

Project Ideas

Business

Dustless anchor drilling service

Offer OSHA Table 1–compliant, dust-extracted drilling for signage, handrails, machinery bases, and fixtures in occupied spaces (offices, retail, healthcare). Market the minimal cleanup, precise placement, and reduced downtime benefits.


Adhesive anchor and rebar doweling subcontractor

Partner with GCs to install epoxy-set anchors and rebar dowels for retrofits, equipment pads, bollards, and structural connections. The hollow SDS‑Max bit speeds hole production and ensures clean holes for better bond strength.


Railing and post-base retrofits

Specialize in installing guardrails, stair rails, pergola post bases, and fence posts into existing concrete/stone. Promote fast, clean installs with reduced dust spread in residential and commercial settings.


Museum/gallery/event install crew

Provide temporary or permanent anchor installs in galleries and event venues where dust control is critical. The airlock-style extractor interface keeps air clean around art and audiences, and holes can be patched post-event.


Dustless drilling kit rental + training

Rent a packaged SDS‑Max hammer, hollow bits, and compatible extractor with quick training on OSHA-compliant workflows. Target small contractors and facility teams who need compliant drilling without buying the full setup.

Creative

Pinned stone garden features

Drill 7/8-inch holes into boulders and existing concrete to pin steps, benches, or edging with rebar or stainless threaded rod set in epoxy. The hollow bit’s dust extraction keeps the site clean and safe while the Y-cutter tip gives precise hole starts on uneven stone surfaces.


Stone-and-wood outdoor table

Create a sculptural patio table by anchoring threaded rod into a concrete pad and into a slab of hardwood or a stone top. The hollow bit speeds anchor-hole drilling and minimizes airborne dust, making fit-up and adhesive curing cleaner and faster.


Stacked-rock fountain or cairn

Build a stable vertical rock feature by drilling alignment holes through stones and pinning them with stainless rod. Dust extraction helps control silica dust while working dry, and the long working length lets you pin taller assemblies securely to a base.


Modular planter wall on masonry

Drill clean, accurately placed holes in block or concrete walls to mount a grid of planter brackets. Use adhesive anchors for a sleek, hardware-light look. The hollow bit reduces cleanup when working around soil and plants.


Hidden mounts for outdoor art

Install concealed anchors in a concrete pad for metal or wood sculptures. The precise start and dust-free drilling make layout easier and protect finishes during installation.
