Condition: new, Year of construction: 2025, CORMAK PT310ECO Thickness and Surface Planer with Spiral Cutter Block – Precision and Work Efficiency The CORMAK PT310ECO is a modern planer-thicknesser engineered for high finish quality, reliability, and low noise levels. Thanks to its spiral cutter block with 30 replaceable carbide inserts, the machine delivers exceptionally smooth surfaces with significantly reduced vibration and noise. Its stable construction and powerful motor make it a versatile solution for professional woodworking—both in carpentry shops and in artisan workshops. Key Advantages Spiral cutter block – 30 inserts (310 × 25 × 3 mm) provide long tool life, precise planing, and reduced noise levels. Massive cast iron work tables – absorb vibrations and ensure stable material feed. High power output – 2.2 kW motor (S1) / 2.6 kW (S6) ensures consistent performance during demanding operations. Large working area – 310 mm planing width and 180 mm height capacity for various workpieces. Effective chip extraction – Ø100 mm extraction port allows easy connection to dust collection systems. Construction and Technology The PT310ECO is equipped with a spiral cutter block of 75 mm diameter, ensuring smooth operation and significantly longer durability than traditional knives. Each insert can be rotated four times, greatly reducing maintenance and operating costs. The planer-thicknesser features wear-resistant cast iron tables: 1290 × 310 mm (planer) and 540 × 310 mm (thicknesser). The adjustable fence angle between 90° and 45° allows for accurate guiding of materials even at an angle. Precision and Performance Maximum cutting depth: Planing mode: 3 mm Thicknessing mode: 4 mm Cutter block rotation speed: 5,500 rpm The machine’s rigid frame enables surfaces that are ready for gluing, lacquering, or further processing. A reliable thickness planer for both mass production and small batch work. Applications The PT310ECO is the ideal solution for: Professional carpentry and furniture workshops Prototyping labs and training centers Industrial maintenance departments Technical schools and trade colleges Standard Equipment Spiral cutter block with 30 inserts Cast iron work tables Cutter head guard Ø100 mm dust extraction outlet Feed switch and emergency stop switch Optional Equipment Mobile base Dust extractor Technical Specifications Specification Value Planer table dimensions 1290 × 310 mm Thicknessing table dimensions 540 × 310 mm Spiral cutter block diameter 75 mm Bwedpew Ab Afofx Abzjw Cutter block speed 5,500 rpm Cutting inserts 310 × 25 × 2.5 mm Fence tilt angle 90°–45° Chip extraction outlet Ø100 mm Maximum thicknessing height 180 mm Max. cutting depth 3 mm (planing) / 4 mm (thicknessing) Motor power (S1 / S6) 2.2 kW / 2.6 kW Maximum workpiece width 310 mm Weight (gross) 200 kg
