Construction Attachments
Keycut - Milling
The KeyCut is a skid steer milling attachment for skid steers that is ideal for patching, utility cuts and trimming.
- 24" and 40" standard cutting width
- Custom drum width options available
- 5" to 8" cutting depth
- Standard, fine and micro drum spacing options
- Tooled with Keystone's Easy Screw Quick-Change Block System
- Electro-hydraulic control of depth, side shift and tilt
- Independent depth skis for precise lap cuts
Flatliner - Precision Grinding
Ideal for -
- Maintenance Work/Bump Grinding
- Ride Quality/IRI Improvement
- Pavement Marking Removal
- Coatings Removal
Skid steer attachment designed to smooth pavement roughness by shaving high spots and other irregularities in a cost effective manner. The Flatliner uses Flat Tooth Technology, a machined and precise holder system to insure a smooth and uniform surface, setting a new industry standard.
- Precise Depth Control
- Variable Cutting Widths: 2" to 49"
- 100% Surface Coverage
- Precisely levels bumps and other irregularities, acts as a profilograph and bump grinder in one
- Utilizes Keystone Engineering's patented Flat Tooth Cutting Techonology
- 100% surface coverage, unlike diamond blades and other traditional carbide conical tools and flail cutters
- Minimal surface damage seen when comparing to traditional carbide tools and water blasting equipment
- No water required
Crack Routing Attachment
Crack Routing Attachment helps reduce material cost and increase production. Attachment utilizes Keystone Engineering's RS Quick-Change Drum System.
- Reduce material cost and increase production
- Route from .5" - 3.75" wide
- Accurate depth adjustment up to 2"
- Ejection system keep debris out of routed area
- Utilizes Keystone's RS Drum System
V-Head - Joint Repair
Skid Steer Attachment Designed for Longitudinal Joint Repair
- Remove and replace at deeper depths on the joint line or other targeted areas
- Requires less material
- Cuts a V-shape into the pavement that allows the new material to bond better to the existing pavement
- The tapered cut alleviates the shearing effect that is seen with the flat surface cuts
Keysaw - Concrete Saw
Skid Steer Saw/Cold Planer Attachment Designed for Cutting Concrete
- Asphalt and Concrete Sawing
- Partial Depth Concrete Repair
- Micro-Trenching
- Longitudinal Joint Repair
Micro-Grinding
- Reduce material cost and increase production
- Grind width between .5" to 2.5"
- Accurate depth control up to 1.5"
- Ejection system keeps debris out of grind area
- Utilizes Keystone Engineering's RS Quick-Change Drum System
Micro-Trenching
Cutting and Trenching Attachment
- Reduce material cost and increase production
- Trench between .5" to 2.5" width
- Accurate depth control up to 1.5"
- Ejection system keeps debris out of trenched area
- Ulitizes Keystone Engineering's RS Quick-Change Drum System

Pavement Marking Removal
- Optional self-contained vacuum system
- 100% surface coverage to eliminate the need for multiple passes during pavement marking removal
- Shaves the pavement's surface instead of impacting the surface like traditional carbide conical tools that are used in asphalt milling machines
- Minimized surface damage during pavement marking removal. Far less damage seen by the Flat Tooth System than by water blasting equipment and traditional asphalt grinding products
- Leaves a level and smooth surface unlike a milled surface or a diamond ground surface

Material Processing
Lab Core Crusher
- Creates material that is representative of field milling
- The crusher's drum design replicates an actual milling machine's drum with similar wrap design, tooth spacing and drum RPM
- Saves time by crushing cores in seconds and eliminates the need for a jaw crusher
Underground Mining
Keysaw Mining - Underground Cutting and Grinding
- Sawing
- Grinding
- Micro Trenching
Aftermarket Drum Manufacturing for all Milling - Keystone will design and build replacement drums for all OEM skid steer attachments to meet any specification or specific need.
- Custom Width Attachment Drums
- Standard, Fine Milling, and Micro-Milling Attachment Drums
- Surface Grinding Attachment Drums
- Rumble Strip Grinding Attachment Drums
- Line Removal Attachment Drums
- Pavement Coatings Removal Attachment Drums
Attachment Drums
- Utilizes Keystone's proven attack and skew tool angles which allows the drum to cut more efficiently and drastically reduces tool consumption
- Machined and balanced shell minimizes vibration on the attachment
- Precise end ring placement with "The Edge" reduces wear on the blocks and leaves a clean edge cut
- Tooled with Keystone's patented Easy Screw Quick-Change System to eliminate the need for in-field welding
- Easy insert removal-unscrew holder with standard tools, no hydraulic presses or special tools required
- Taper on taper design provides a consistent holder locking depth, providing a uniform milled surface
