SDS Max 4-cutter carbide drill bit designed for use in rotary hammers. The bit is produced using a heat/strengthening process (referred to as IRON BLAST™) to improve fatigue resistance. It has a full carbide head with a 4-cutter geometry intended to extend service life and to better resist contact with reinforcing steel. The bit includes a wear mark to indicate remaining usable diameter and is covered by a manufacturer no-break replacement policy while the wear mark is visible (exclusions apply).
Project Ideas
Business
Anchor Hole & Rebar Doweling Service
Offer mobile drilling for epoxy-set anchors and rebar dowels in existing slabs, walls, and footings. The 1-3/8 in bit size suits larger threaded rod and sleeve systems; the 24 in working length reaches deep embedments. Sell per-hole pricing with add-ons (epoxy injection, rebar supply, pull testing). The wear mark provides an auditable hole-diameter check for QC.
Retaining Wall Drainage Retrofits
Specialize in adding weep holes and drain sleeves to CMU and poured-concrete retaining walls to alleviate hydrostatic pressure. Use the SDS Max bit for fast penetrations, then install sleeves, gravel pockets, and fabric filters. Package with wall inspections and French drain tie-ins for a high-value upsell.
Natural Stone and Bedrock Anchoring
Provide drilling and pinning of landscape elements—steps, boulder features, rail posts, and sculpture bases—directly into stone or bedrock. The full-carbide 4-cutter head excels in hard aggregate; offer turnkey service with stainless or epoxy-coated dowels, non-shrink grout, and concealed caps.
Masonry Conduit Pass-Throughs
Partner with solar, HVAC, and low-voltage contractors to drill clean 1-3/8 in penetrations for 1 in EMT/PVC sleeves through brick, block, and concrete. The long bit handles thick walls; finish with sleeves, firestop, and exterior sealing. Bill per penetration with tiered pricing for depth and access complexity.
Safety Rail and Guard Anchor Retrofits
Install code-compliant anchor holes in existing concrete for guardrails, handrails, and machine safety barriers. The bit’s rebar-strike resilience reduces downtime in reinforced slabs. Offer layout, drilling, epoxy or mechanical anchoring, and load documentation to facilities and GC clients.

Basalt Column Bubbling Fountain
Use the 29 in working reach to bore a deep 1-3/8 in channel through a basalt column or glacial boulder for pump tubing and wiring. The 4-cutter carbide head handles hard inclusions and occasional rebar if you repurpose a reinforced concrete piece. Finish by epoxying a short sleeve at the base to protect tubing and seat the column over a hidden basin.
Rock-Anchored Garden Steps
Drill 1-3/8 in holes into bedrock or large boulders to pin timber or precast concrete treads using epoxied rebar or threaded rod. The long working length lets you set deep, reliable dowels for staggered steps and small landings, creating a natural-look pathway anchored directly to the site.
Concrete Fire Pit Airflow Ring
Add a ring of 1-3/8 in intake holes around the base of a precast or cast-in-place concrete fire pit to improve combustion and reduce smoke. The 4-flute design clears dust quickly in thick walls; mark and space holes evenly, break edges with a chamfer, and add stainless mesh behind each hole to keep embers in.
Reclaimed-Concrete and Timber Bench
Turn a reclaimed concrete slab or block into a sculptural bench by drilling 1-3/8 in mortises to accept hardwood or steel legs. The wear mark helps you keep a consistent diameter for a snug, epoxy-set fit. Add a slight countersink for decorative ferrules and a clean, modern finish.
Modern Light Bollards
Create minimalist outdoor light bollards from solid concrete blocks: drill a vertical cable chase and side ports for light spill. Sleeve the chase with PVC, pull low-voltage wiring, and set frosted acrylic lenses over the ports. The bit’s rebar-resistant head is useful if you upcycle reinforced blocks.
