Mag Drill Cleaning and Storage Checklist

Shut down before treating chips as cleaning

Follow the exact shutdown sequence and wait for the spindle to stop. Hougen says to confirm slug ejection and clear chips from the cutting tool and from around and beneath the magnet after a hole. Milwaukee 2787/2788 tells the operator to use pliers after the spindle stops, keep hands, gloves, rags and clothing away from moving parts, and avoid damaging the cutter teeth.

Remove the battery or disconnect power where the exact manual requires it before maintenance or accessory changes. A hot slug, sharp chips or a loaded ejection pin is not ordinary dust. Keep the possible ejection path away from people and do not pack a cutter with a retained slug into the case.

Clean the Milwaukee 2787/2788 by its own rules

The Milwaukee manual says to clean dust and debris from vents and keep the tool clean, dry and free of oil or grease. It permits mild soap and a damp cloth. It prohibits immersing the tool, battery or charger or allowing liquid inside, and warns that gasoline, turpentine, lacquer thinner, paint thinner, chlorinated solvents, ammonia and ammonia-containing household detergents can harm plastics or insulated parts.

That is an exact-model cleaning boundary, not a universal chemical list for every mag drill. Another machine needs its own manual. Likewise, a cutting fluid approved at the cutter is not automatically a housing cleaner, contact treatment or storage coating.

• Clear vents without forcing debris or liquid into the housing.
• Keep handles and control surfaces dry and free of oil or grease.
• Keep battery and charger care separate from cutter-fluid cleanup.

Inspect before labeling the kit ready

Record undue noise, interrupted cutting, misalignment or binding, broken parts, a lifting magnet, damaged tooling or a fluid leak while the event is still clear. Milwaukee directs 2787/2788 users to service when a condition may affect operation and says repairs belong with a Milwaukee service facility. Cleaning must not hide an unresolved fault.

Milwaukee also specifies a service-facility inspection after six months to one year depending on use for those exact tools. Do not convert that sentence into a universal annual service interval for corded Hougen, Evolution, DEWALT, FEIN or Makita machines. Their own manuals and actual use set their maintenance actions.

• Check the guard, restraint and base contact surface.
• Keep cutter and pilot markings legible and paired.
• Quarantine damaged, leaking or unidentified items.
• Record missing consumables before the next job.

Store drill, battery, tooling and fluid as separate items

Return small parts to labeled compartments, protect sharp edges and keep loose metal away from controls, cords and battery terminals. The Milwaukee manual says an unused battery pack must be kept away from metal objects that could bridge its terminals. Removing the battery for storage is not permission to leave the tool wet, oily or unresolved.

For S28MAG/EVOMAG42 transport, Evolution says to lower and lock the slide, remove the cutter, close the coolant tap or drain the system, use the carrying handle and secure the drill on its side in a vehicle. Those are exact transport steps, not a universal long-term storage sequence or proof that every machine must always be drained.

Cap and store cutting fluid according to its product instructions rather than leaving a connected bottle free to leak into the case. Keep exact cutter, pilot, shank and depth identities together. A dry, weather-protected, organized case supports the next inspection; it does not prove the machine is serviceable after a slip, stall, leak or abnormal noise.
