Ultra Tool & Round Tool Carbide Cutting Tools
Shop USA-made Ultra Tool and Round Tool cutting tools at Suncoast Precision Tools for milling, drilling, hole finishing and specialty machining. Explore carbide end mills, drills, reamers, routers, burrs and profile tools, with inch and metric options across the range. Compare the size, geometry, coating and work-material recommendations for your application, then check the exact part number and available stock before ordering.
Carbide End Mills for Everyday Machining
Shop Ultra Tool and Round Tool end mills in inch and metric sizes. General purpose choices include 2-, 3- and 4-flute tools with square, ball nose and corner radius ends. Compare diameter, cutting length, flute count and coating, then choose the geometry for slotting, profiling or finishing. N/C tolerance end mills provide a separate option for specified keyway work.
End Mills for Aluminum & Non-Ferrous Materials
Explore 2- and 3-flute carbide end mills for aluminum and other designated non-ferrous materials. The range also includes Series 313CF coolant-fed roughers for aluminum. Match flute space, cutting length and end geometry to the operation, and check the selected tool's coating and coolant requirements before choosing speeds and feeds.
Milling Steel, Stainless Steel & Titanium
Compare Series 323 and 365 SmoothFlute variable-helix rougher/finishers with Series 355 and 377 variable-pitch finishers. Series 395 adds sinusoidal roughing tools for designated steels, stainless steels and high-temperature alloys. Choose the series for the alloy, roughing or finishing strategy, and machine setup; material recommendations vary by tool.
Solid Carbide Drills & Center Drills
Find jobber, stub, parabolic, straight-flute and specialty carbide drills, plus micro drills, spotting drills and combined drills and countersinks. Compare the drill diameter, flute length, overall length and point geometry. Select a tool with adequate usable depth and chip clearance for the hole, and check its recommended materials and cutting conditions.
Carbide Reamers & Hole Finishing
Browse fractional and metric straight-flute reamers for finishing prepared holes. The selection includes standard-length carbide tools and longer carbide-head tools with steel shanks. Match the reamer diameter, flute length and shank to the job. For flat-bottom recesses and countersunk features, compare the separate counterbore and countersink ranges.
Chamfer Mills, Corner Rounders & Drill Mills
Choose carbide chamfer mills for angled edges, corner rounders for specified external radii, or drill mills for operations supported by their cutting geometry. Match the angle or radius to the drawing, then check the tip, pilot, cutting diameter and shank dimensions. Included angle and angle per side describe different measurements; use the listing that matches your specification.
Carbide Routers for Composites & Plastics
Explore compression and downshear routers for designated composite and CFRP applications, fiberglass cutters and single O-flute routers for plastics. Choose the cutting style for the material and required edge condition. Compare cutting diameter, usable length and flute geometry, and follow the individual series' application guidance for the laminate or plastic being machined.
Carbide Burrs & Finishing Tools
Shop carbide burrs, also called rotary files, for deburring and material removal. Compare head shape, cut style, cutting diameter and shank size for the material and access available. The range also includes burr sets, internal grinding tools and piloted die trimmers. Check the operating recommendations for the exact tool and equipment.
Keyseat Cutters, Engravers & Boring Bars
Find keyseat cutters for specified slot widths and diameters, carbide engravers for detail work, and jig boring bars for internal features. Compare cutter width and neck clearance on keyseat tools, tip form and angle on engravers, and minimum bore and usable depth on boring bars. Each tool family has its own dimensional requirements.
Micro Tools, MONOLITH Reach & Round Tool Hard Milling
For small features, compare micro-size solid carbide and CBN-tipped end mills. MONOLITH reduced-neck end mills provide extended-reach options. Round Tool DM and HT families address designated hard die, mold and heat-treated materials. Check the individual tool's substrate, hardness range, reach and end geometry; a series recommendation does not apply to every cutter on this page.
Choose the Geometry, Coating & Reach
Start with the operation, exact work material and finished feature. Compare diameter, cutting length, overall length, shank and end style before selecting a coating. Tool Alliance technologies include SmoothGrind cutting-edge finishes, SmoothContricity precision tooling, SmoothCoat coatings and SmoothEdge edge preparation. Availability varies by product. Review the selected item's specifications and catalog guidance when matching a replacement.
Carbide Blanks for Toolmaking
The line also includes cylindrical carbide blanks and double-ended split blanks. These are separate from finished cutting tools. Select the blank diameter, overall length and form for your toolmaking requirements, then confirm the specifications before ordering.
Ultra Tool & Round Tool Selection Questions
- Are Ultra Tool and Round Tool products made in the USA?
- Suncoast identifies the Ultra Tool and Round Tool lines on this page as USA-made. Review the country-of-origin information on the exact product when your purchase requires item-specific documentation.
- Does this page include both Ultra Tool and Round Tool?
- Yes. The end mill range includes both brands. Use the Brand and Series filters where available to narrow the selection, then compare the exact part number and specifications.
- Which end mill should I choose for aluminum or stainless steel?
- Begin with the dedicated aluminum and non-ferrous range for suitable aluminum jobs. For stainless steel, compare the listed steel, stainless and titanium milling families. Check the exact alloy, cutting strategy, coating and series guidance before choosing the tool.
- What is the difference between cutting length and reach?
- Cutting length describes the fluted cutting portion. Reach describes access to a feature and may include a relieved neck below the shank. A longer overall tool is not automatically suitable for a deeper cut. Compare cutting length, length below shank, neck clearance and overall length together.
- Are all of these tools solid carbide?
- The range is primarily carbide cutting tools, but construction varies. It also includes CBN-tipped micro tools and certain reamers with carbide cutting heads and steel shanks. Check the substrate and construction listed for each part.
- How do I check stock and order the correct tool?
- Search by the full manufacturer part number, confirm the brand, series, size and coating, and review the local or factory stock information shown for that item. Availability varies by part number and quantity. Use the linked categories and catalog specifications to confirm the configuration before ordering.
