DeWalt DCP580N 18V XR Brushless 82mm Cordless Planer

In-Depth Look

The DeWalt DCP580N is an 18V cordless planer for removing small amounts of material from timber, such as easing doors, trimming linings and chamfering edges.

Door Fitting

The 9mm rebate capacity allows door edge rebates to be cut with the planer, and the 0.1mm depth adjustment lets you set the amount of material removed. When you are taking off 0.5mm to ease a binding door, fine adjustment helps avoid removing too much and leaving a visible gap. Being cordless, there is no lead trailing across finished floors.

Blade Economy

The twin reversible TCT blades give four cutting edges before you need a replacement set. Tungsten carbide tipped (TCT) edges are generally chosen for their wear resistance, including on MDF and harder timbers. Follow the manual for reversing and replacing the blades.

Dust and Chip Management

Chips eject from either side via a switchable deflector, which directs the output away from the user and finished surfaces. A dust bag can be connected for cleaner working inside, though it is sold separately.

Depth Settings

The front shoe height relative to the rear shoe determines the depth of cut, with 0.1mm increments from zero to 2mm maximum. The V-groove running lengthways in the front shoe helps when chamfering edges.

Summary

The DCP580N combines an 82mm blade width, 9mm rebate capacity, 0.1mm depth adjustment and twin reversible TCT blades on DeWalt’s 18V XR battery platform. It suits joiners and carpenters who fit doors and trim timber on site, as a bare unit with battery and charger bought separately.

How It Compares

The DeWalt DCP580N is a cordless planer on the 18V XR platform, sold as a bare unit, so the battery is bought separately. It has an 82mm planing width, a maximum depth of cut of 2mm, a rebating depth of 9mm and fine adjustment in steps of 0.1mm. The brushless motor runs at about 15,000rpm with no load, and the blades are reversible tungsten carbide tipped. Retailers list the weight at about 2.5kg.

Planing is only one way to take material off a door or an edge. This table sets the planer against the alternatives.

For easing a binding door, a planer lets you take off small amounts and try the door between passes. For forming a rebate, the 9mm depth lets you cut a step along an edge in one tool. Check the manufacturer’s data for the exact settings on the model you buy.

If you already own DeWalt 18V XR batteries, a bare unit adds a planer to the platform you have. If you are starting from scratch, compare the whole platform, not only the planer.

Common Questions

How do I ease a binding door with a power planer? Close the door and mark where it rubs, then lift it off and set the planer to a shallow cut. Take light passes along the high spot, refit the door and test it before taking more off. Ease the leading edge of the door slightly so it clears the frame. Seal any bare edges afterwards, as bare timber takes up moisture.

What does the 2mm depth setting mean? It is the maximum thickness the blades remove in one pass. You do not have to use it. Most door work calls for a much shallower cut and several passes, and the 0.1mm fine adjustment helps you set it.

What is a rebate and why does 9mm matter? A rebate is a step cut along the edge of a piece of timber, often so another piece can sit in it. The 9mm rebating depth is the deepest step this planer can cut, so check that it covers the joint you plan to make.

How do I change or turn the blades? The blades are reversible and tipped with tungsten carbide, so when one edge is worn you can turn the blade over. Take the battery out first, then follow the manual for the exact method.

What should I check before planing reclaimed timber? Look for nails, screws and grit. Metal and grit damage blades, so remove it or avoid that part of the board. Always take the battery out before touching the blades, and follow the manufacturer’s instructions.
