Surface leveling and grinding for flatness requirements
Removal of existing coatings, adhesives, and surface contaminants
Polished concrete floor creation in commercial spaces
Terrazzo and stone floor restoration and finishing
Edge and corner grinding in confined areas
Selecting the Right Keiser Grinder
E850 Floor Grinder: Primary choice for large area concrete and stone work
E180 Handheld: For edges, stairs, corners, and detail grinding
DS3000 Sanding: For floor sanding and finishing operations
ES250 Scarifier: For aggressive removal of coatings and surface preparation
Consider area size: E850 covers large floors efficiently
Evaluate power supply: E850 requires three-phase, others single-phase
Match disc selection to material and desired finish
Assess accessibility: Handheld for confined spaces, floor units for open areas
Avoid These Common Mistakes
- Using incorrect RPM for the grinding stage and material
- Neglecting overlapping passes causing visible lines
- Applying excessive pressure instead of letting weight do the work
- Skipping grit sequences when progressing to polish
- Ignoring dust collection affecting visibility and health

Frequently Asked Questions
The E850 is designed for large-area floor grinding including concrete preparation, coating removal, surface leveling, and polished concrete creation. With its 850mm working width, four-head design, and 15kW motor, it's ideal for commercial and industrial floor projects where efficient coverage is essential.
The four grinding heads are arranged to overlap their grinding paths, ensuring complete coverage with no gaps or lines between passes. This crosswise running pattern maintains constant grinding pressure across the full 850mm width, producing even results without requiring multiple overlapping passes.
The E850 requires three-phase power to drive its 15kW motor. The built-in frequency converter allows variable speed control from 300-1800 RPM while providing motor overload protection. Ensure appropriate three-phase supply is available before scheduling E850 work.
The E180 handheld grinder is essential for areas the E850 cannot reach—edges along walls, corners, stair treads, and confined spaces. It provides the same grinding capability in a maneuverable handheld format for complete floor preparation coverage.
The ES250 electric floor scarifier is designed for aggressive surface removal—stripping old coatings, removing adhesives, and preparing heavily contaminated surfaces. It removes material faster than grinding for initial preparation before grinding and polishing stages.
Start with coarse diamond tooling to remove imperfections and open the surface, progressively moving through finer grits. The E850's variable speed allows adjustment for each stage. Multiple passes with increasingly fine tooling produce the desired polish level, typically finishing with 1500-3000 grit for high shine.
Regular maintenance includes checking and replacing grinding discs as they wear, cleaning dust from the machine especially around the motor, inspecting the folding handle mechanism, and verifying the frequency converter operation. Follow manufacturer guidelines for motor and drive system servicing.
Keiser grinders are designed to connect with dust extraction systems. Proper dust collection is essential for operator health, visibility, and achieving quality finishes. Specify appropriate dust extraction equipment when planning grinding projects.
Keiser Industrial Grinding Equipment
Keiser grinding machines address the demanding requirements of professional floor preparation and finishing. From heavy concrete grinding to fine polishing, their equipment range covers the complete surface preparation workflow with machines engineered for efficiency, durability, and professional results.
E850 Floor Grinding Power
The E850 represents Keiser's flagship floor grinding capability. The 15kW three-phase motor drives four overlapping heads fitted with twelve 4-inch grinding discs, covering 850mm in a single pass with no gaps. At 386kg, the machine's weight provides consistent grinding pressure without operator effort, while variable 300-1800 RPM speed suits different grinding stages.
Overlapping Head Design
The four-head overlapping arrangement eliminates the common problem of visible lines between grinding passes. Each head's coverage overlaps with adjacent heads, maintaining constant pressure across the full width. This design reduces passes required and produces uniform results that meet professional flooring standards.
Integrated Control System
The folding handle incorporates a central control panel for convenient operation. The built-in frequency converter provides smooth variable speed control while protecting the motor from overload conditions. This integration puts all controls within easy reach while maintaining the machine's professional capabilities.
Complete Surface Preparation Range
Beyond the E850, Keiser provides equipment for the complete surface preparation workflow. The E180 handheld grinder handles edges and confined spaces, the ES250 scarifier tackles aggressive removal tasks, and the DS3000 addresses sanding requirements. This comprehensive range enables professional operations from initial preparation through final finishing.
Variable Speed Versatility
The 300-1800 RPM speed range accommodates different grinding stages and materials. Lower speeds suit aggressive initial grinding and softer materials, while higher speeds enable efficient polishing passes. This versatility allows one machine to handle the full grinding and polishing progression.
