Hammer HS 950 Edge Sander
The Hammer HS 950 is an oscillating edge sander manufactured by the Felder Group under their Hammer brand of woodworking machinery. Introduced as an entry-level machine for professional and serious hobbyist woodworkers, the HS 950 is designed to provide high-quality edge sanding capabilities with features typically found in more expensive industrial machines.
The HS 950 features a 2515 mm × 150 mm (approximately 100 inches × 6 inches) sanding belt mounted on a solid cast iron frame with a 950 mm (37.4 inch) sanding support length. A key feature of the machine is its switchable belt oscillation, which enables maximum use of the entire sanding belt surface and significantly extends belt life. The machine is powered by a 2.2 kW (3 HP) motor and operates at a belt speed of 17 m/s.
One of the distinguishing characteristics of the HS 950 is its open design, which facilitates the sanding of lengthy or oversized workpieces. The sanding unit can be continuously tilted from 0° to 90° relative to the table, providing flexibility for different sanding operations. The solid cast iron worktable can be adjusted in height by up to 150 mm (5.9 inches) using a handwheel, allowing operators to utilize the entire height of the sanding belt and further extending the belt's service life.
The machine also includes an additional table specifically designed for cylindrical sanding of radii greater than 60 mm. For precision work, the main worktable features a T-slot running its entire length, which accommodates an optional mitre fence for accurate angular sanding.
The Hammer HS 950 is positioned in the market as an affordable yet high-quality alternative to more expensive industrial edge sanders. It is particularly valued by small to medium-sized woodworking shops, furniture makers, and serious hobbyists who require professional-grade edge sanding capabilities without the investment in industrial machinery. Users have noted the machine's excellent dust collection capabilities, robust construction, and versatility as notable advantages.
The HS 950 is part of the Hammer line of woodworking machinery within the Felder Group, which has been producing affordable yet reliable woodworking machines since 1997. The Felder Group, founded in 1956, is known for manufacturing high-quality woodworking machinery and has established itself as a reputable brand in the woodworking industry.

Key Features
The Hammer HS 950 stands out with several distinctive features that enhance its functionality and ease of use:
Oscillating Sanding Belt
The switchable sanding belt oscillation is a key feature of the HS 950. When enabled, the oscillation mechanism moves the belt vertically within a 5 mm range while sanding, ensuring maximum use of the entire sanding belt surface. This feature significantly extends belt life and produces a more consistent finish. The oscillation can be easily turned on or off via a dedicated lever, allowing the operator to customize the sanding pattern according to the specific requirements of each project.
Height-Adjustable Cast Iron Worktable
The solid cast iron worktable can be conveniently adjusted in height by up to 150 mm using a handwheel mechanism. This feature allows operators to utilize the entire height of the sanding belt, further maximizing belt life and versatility. The height adjustment also makes it easier to position workpieces of varying thicknesses for optimal sanding results.
Continuously Adjustable Sanding Unit Tilt
The sanding unit can be continuously tilted from 0° to 90°, providing enormous flexibility for different sanding operations. This allows for edge sanding, chamfering, and face sanding with the same machine. Preset end stops at key positions ensure accurate and repeatable angle settings. The current angle can be read on the side swing scale, and a dedicated hand grip facilitates smooth operation.
Additional Table for Cylindrical Sanding
On the left side of the machine, there is a supplementary table designed for sanding radii greater than 60 mm. This table is also height-adjustable, making it ideal for working with curved and rounded workpieces. The additional table significantly expands the range of sanding operations possible with the machine.
Open Design for Long Workpieces
The open design of the HS 950 allows for easy sanding of lengthy workpieces. For extra-long pieces, the extraction flap can be swung upwards, extending the machining area and creating more space to work with oversized materials.
T-Slot for Accessories
The main worktable features a T-slot running the entire length of the table, accommodating accessories such as the optional mitre fence. This 15 mm slot allows for secure workpiece positioning and precise angle sanding operations, enhancing the machine's versatility for various woodworking applications.
Efficient Dust Collection
The HS 950 features excellent dust collection capabilities, with minimal peripheral dust during operation. The machine includes a dedicated dust extraction connection with a diameter of 120 mm, designed to effectively remove sanding dust and maintain a clean working environment.
Safety Features
The Hammer HS 950 incorporates several safety features to protect the operator during use:
Rear cover for the abrasive belt to prevent contact with the rotating belt
Infeed fence that serves as a workpiece stop to prevent workpieces from being thrown backwards
Emergency stop button for immediate machine shutdown
Secure locking mechanisms for all adjustable components
