Watch our ironworker tooling in a full performance test. See how our factory-made punches, dies, and shearing blades work with great precision and efficiency. This demo shows our tooling’s reliability across 3 key stations—ideal for pros needing durable, high-performance tools.
Punch clean, easy holes in thick heavy-duty steel plates
Uses our heat-treated ironworker punches
No jagged edges, consistent hole alignment
Saves time and reduces rework
Cut flat bars and angle iron smoothly, no burrs
Features sharp D2/SKD11 replacement shearing blades
Fast cutting without losing quality
Boosts productivity for your ironworking tasks
Make precise 90-degree and V-notches
Perfect alignment, little material deformation
Consistent results for every notch
Ideal for professional ironworking projects
9CrSi: Budget-friendly, general-purpose option for light to medium work
Cr12MoV: Standard choice for most punching, shearing, and notching tasks
DC53: High-performance upgrade for heavy, high-volume production
D2 Steel: Keeps shear blades sharp longer, reducing tool changes
Our tooling is CNC-ground to tight tolerances for perfect punch-die alignment
Produces "bolt-ready" holes with no extra grinding needed
Minimizes workpiece damage (no distortion or rough edges)
Works for all common tasks: punching, shearing, notching, and custom jobs

Kingsland
Round Punches & Dies: For bolting and assembly
Oblong & Square Tooling: For slotting and architectural work
Shear Blades: For angle iron, flat bar, and c-channel
Notching Tools: For clean corner cuts
We make custom-sized tooling for unique project needs
Large inventory of standard sizes (fractional and metric)
Protective packaging + anti-rust coating for safe shipping
Fast global shipping to keep your shop running
Use 1/32” clearance for most materials (adjust for thickness/alloy)
Proper clearance = clean cuts, less machine strain, and longer tool life
Never run tools dry—lubrication reduces friction and heat
Extends tool life by up to 50% (critical for stainless/tough steels)
Misalignment causes tool breakage and poor results
Inspect punch holders, die blocks, and ram alignment often
Dull or chipped die edges
Material buildup on punches
Excessive burrs on holes
Strange noise/vibration during use
Inconsistent hole size/shape
Durable: Built for heavy-duty, non-stop use
Cost-effective: Fewer replacements = less downtime and lower costs
Flexible: Standard sizes + custom options
Convenient: Universal compatibility and fast shipping
Material | Applicable Working Conditions | Core Advantages | Core Disadvantages |
9CrSi | Light-duty machines, ≤5mm thin/soft materials, small-batch | Good toughness, low cost, entry-level general-purpose | Average wear resistance, not for thick/high-strength conditions |
Cr12MoV | Small-medium tonnage, ≤10mm ordinary steel/profiles, regular batch | High cost-effectiveness, wear-resistant, small deformation, strong versatility | Average high-impact resistance, not for thick/hard materials |
DC53 | Small-medium tonnage, 8-15mm medium-thick/low-alloy steel, complex profiles | High toughness, wear-resistant, stable quenching, longer service life | Slightly higher cost than Cr12MoV, upgraded pricing |
