StewMac Fret Slotting Table Saw Blade
The StewMac 6″ fret slotting blade is engineered for precision. Its 100-tooth steel construction targets a 0.023-inch fret slot with high accuracy, making it ideal for standard steel-fret guitars. The hollow-ground edge reduces tear-out and fosters smoother slots, which is essential when slotting for accurate intonation and clean fretwire seating. A key design advantage is the no-stiffener requirement; the blade grind adds stability during cutting, simplifying setup and reducing variables that could affect slot accuracy. This blade suits both professional luthiers and serious hobbyists seeking consistent, repeatable results.
Usage notes: align the blade with the neck and fretboard landmarks, ensure the neck is securely clamped, and feed with steady control to maintain slot width and depth. The 0.023″ width is compatible with standard fretwire diameters, but always verify fretwire size for your specific build. Regular inspection of the blade edge helps prevent subtle deviations in slot dimensions over multiple slots.
Guitar Fretting Fret Slotting Saw
This American-made fretting saw from C. B. Gitty emphasizes straightforward operation and practical design. With an 18 TPI configuration, it’s tailored for clean slotting in a variety of stringed instruments, including guitars and cigar box guitars. The 1 3/4″ total cut depth provides enough reach for typical necks while maintaining control. Teeth are angled to cut on the push stroke, which can simplify the workflow and help guide straight slots. For builders who value local manufacturing and a dependable 1-step approach, this blade offers a balanced option.
Considerations include the compatibility with your fretwire width and the ease of handling during repeated slots. The tooth geometry can influence tear-out resistance, so testing on a scrap neck might be prudent before working on a finished instrument. This blade pairs well with standard fretwire gauges used in many luthier shops.
StewMac Japanese Fret Slotting Saw
The StewMac Japanese fret slotting saw combines traditional craftsmanship with a practical build. This exclusive option is designed for efficient fret slot cutting and is paired with a depth stop to help achieve consistent slot depths across multiple frets. The pull-stroke cutting action typical of Japanese saws offers controlled, precise results when slotting, reducing wander and tear-out. The depth-stop feature is particularly helpful for maintaining uniform slots, which is critical for proper fret seating and intonation.
For users who value traditional tool design and a robust cutting action, this blade provides a reliable workflow. Pair it with quality fretwire and a stable work surface to maximize slot uniformity across the fingerboard.
Pegas SK7 Fret Saw Blades
Pégas SK7 fret saw blades are widely used with fretting saws, including Knew Concepts models. This listing features two dozen skip-tooth blades with a 15 TPI and .050-inch width, paired with a blade thickness of .015 inches. They are designed as the blade included with Knew Concepts fret saws, making them a compatible and convenient upgrade for users of those systems. The skip-tooth configuration helps reduce chip-out in harder woods and can improve slot quality on more textured fretboard surfaces.
When selecting blades, consider your neck wood type (e.g., maple, rosewood, ebony) and fretwire material. For some woods, alternate tooth geometry may yield marginally cleaner slots, so having a selection can be beneficial for long-running projects.
ALS Guitar Fret Slotting Saw with Depth Stop
Made in Sheffield, this 10″ English-tempered steel fret slotting blade emphasizes durability and accuracy. The included adjustable depth guide allows precise control over slot depth, which is essential when cutting slots to accommodate different fretwire thickness. The 0.023″ (0.58mm) width of cut is a standard dimension that fits most traditional fretwire sizes, supporting consistent seating and intonation. The robust construction is well-suited for repeated use in a busy shop environment, where steady performance over many necks matters.
Users should ensure proper clamping, align the depth stop with the neck’s profile, and regularly verify slot width as you progress along the fretboard. The combination of depth control and a precise cut width makes this blade a reliable option for professional setups and custom builds alike.
TUOREN Guitar Slot Saw Blade Tool Kit
The TUOREN toolkit provides a versatile set of blades with varying tooth distances, plus a mounting handle for convenient changes during fretwork. This kit is designed to improve efficiency when slotting or cleaning frets and bridges on most guitar necks. The blades are engineered from quality metal and the handle is a durable, comfortable option for long sessions in a luthier shop. Users can swap blades to fit different fretwire widths, helping maintain slot integrity across diverse builds.
Potential considerations include ensuring the blade thickness and tooth spacing align with your fretwire and neck wood. The kit is particularly suitable for shops that service a wide range of guitar styles and fret sizes, offering adaptability and ease of use.
Knew Concepts 125.005 MK III Fretting Saw Set
This MK III fretting saw setup emphasizes a tensioned, rigid frame to minimize blade deflection and maximize slot accuracy. The aluminum frame is light yet stiff, with a red anodized finish. The tensioning system uses a knurled knob to achieve about 40 pounds of blade tension, reducing blade breakage under heavy cuts. Included are 12 Pegas #7 15 TPI blades, designed to work with the Knew Concepts saws. The combination supports clean, straight cuts with stable tension throughout a session, which is vital for consistent fret-slot width and fit.
Shop considerations include blade compatibility with your fretting saw model, tensioning ease, and whether you prefer a lightweight frame that still offers robust rigidity on longer necks. This setup suits professional environments where blade stability directly influences slot quality and instrument playability.
Buying Guide: Key Purchase Considerations For Fret Slotting Blades
- Slot width and fretwire compatibility: Most standard frets use 0.023″ slots; confirm your fretwire size before choosing a blade.
- Cutting action and tooth geometry: Hollow-ground, skip-tooth, and pull-cut designs each affect tear-out and control; choose based on wood type and user comfort with your tool.
- Depth control: Depth stops or adjustable guides help maintain uniform slot depth across multiple frets, improving intonation reliability.
- Material and durability: High-quality steel or tempered blades resist wear during multiple necks; consider English-tempered or Japanese steel for longevity.
- Tool compatibility: Ensure blade dimensions align with your fret saw or table saw setup (e.g., Knew Concepts, StewMac, or similar systems).
- Ease of maintenance: Look for blades that are easy to sharpen or replace when slots drift or slots chip during heavy cutting.
- Workholding and ergonomics: A stable clamping system and comfortable handling reduce the risk of accidental mis-cuts and improve precision over long sessions.
- Wood species considerations: Softer woods (walnut, maple) may tolerate simpler tooth geometry, while harder woods (rosewood, ebony) may benefit from more robust blades with smoother edge finishes.
- Cost and availability: A mix of blades can cover a range of projects; consider starting with one reliable, mid-priced option and adding specialty blades as needed.
- Safety and protection: Always wear eye protection and secure the neck firmly to prevent kickback or slips during slotting.
