KEO Cutters: Center Drills, Countersinks & Milling Tools
Shop KEO cutting tools from ARCH Cutting Tools at Suncoast Precision Tools. Explore center drills, countersinks, counterbores, end mills, keyseat cutters, slitting saws and specialty tools for machine shops and toolrooms. The range includes HSS, cobalt, solid carbide and selected PCD tooling. Use the product categories below to compare dimensions, tool materials and coatings, then check the exact part number and available stock before ordering.
Center Drills & Spotting Drills
Browse plain, bell, Hey, jigbore, radius and long-length center drill styles, along with metric options and sets. For spotting operations, compare the separate HSS, M42 and carbide spotting drill range. Select the drill diameter, body diameter, point or included angle, and overall length for the feature you need.
Countersinks, Center Reamers & Counterbores
Compare KEO countersinks and center reamers by included angle, diameter, flute style and tool material. The selection includes three-flute EURO-style and ZERO-flute cobalt countersinks, plus countersink sets. For flat-bottom screw-head recesses, use the separate counterbore range and match the screw size, cutter diameter and pilot.
Carbide, Miniature & PCD End Mills
Find KEO end mills for milling small features, profiles and pockets. The range includes carbide end mills, HSS and cobalt miniature tools, and PCD end mill options. Compare square, ball and corner-radius ends, single- or double-ended construction, cutting length and reach. Choose the tool material and geometry for the specific workpiece.
Chamfer Mills, Drill Mills & Engravers
Choose carbide chamfer mills for angled edges, drill mills for operations supported by their geometry, and engraving or marking cutters for fine detail. Compare the included angle, tip shape, tip size, cutting diameter and flute count. Use the exact dimensions in the listing to match the tool to the drawing.
Keyseat Cutters & Keyway Tools
Shop shank-style keyseat cutters in HSS, M42 and carbide, plus keyseat cutter sets and arbor-style options. Match cutter width and diameter to the keyway or slot. Compare neck clearance, shank or arbor-hole size, tooth configuration and cutting direction so the cutter fits both the feature and your setup.
Dovetail, T-Slot & Angle Cutters
Explore dovetail cutters, T-slot cutters, and single- or double-angle shank cutters for shaped slots and profiles. Check the included angle, head diameter, cutter width and shank dimensions. Available tool materials vary by family, including HSS, M42 and carbide-tipped dovetail tools. Confirm the clearance needed to reach the finished feature.
Corner Rounding & Radius Cutters
Compare double-ended carbide corner rounders with HSS and M42 shank-style corner rounding tools. Concave and convex radius cutters provide additional profile options. Match the radius, pilot or head diameter, cutter width and mounting dimensions to the part. Shank-style and arbor-style cutters require different holders and clearances.
Arbor Cutters & Slitting Saws
Browse plain milling cutters, shell mills and slotting mills, along with jewelers, plain slitting, screw-slotting and side-cut saws. Compare cutter diameter, width, tooth count and arbor-hole size. The range also includes arbor-style angle and radius cutters. Select the cutter form and mounting dimensions for the slot or profile.
Carbide Burrs & Burr Sets
Find KEO carbide burrs, also called rotary files, for deburring and shaping. Compare head shape, cutting diameter, length of cut, shank diameter and tooth configuration for the work material and access available. Burr sets provide multiple shapes in one selection; review the individual set contents before ordering.
Micro Tools for Small Features
The KEO range includes miniature end mills, small spotting drills and carbide circuit-board micro drills. These families serve different operations. Check the minimum diameter, cutting length, shank size and application information for the exact tool, especially when working on delicate or closely spaced features.
Match the Material, Geometry & Mounting
Begin with the workpiece material and finished feature, then compare substrate, coating, cutting dimensions and holding method. For countersinks, distinguish included angle from angle per side. For keyseat cutters and saws, check cutter width and clearance as well as diameter. Review the KEO/ARCH catalog for the selected series before setting cutting conditions.
KEO Tool Selection Questions
- What cutting tools are included in the KEO line?
- Suncoast lists center drills, spotting drills, countersinks, counterbores, end mills, chamfer mills, drill mills, engravers, keyseat cutters, dovetail cutters, T-slot cutters, radius tools, arbor cutters, slitting saws and carbide burrs. Use the linked categories to compare the available sizes and styles.
- Are all KEO tools solid carbide?
- No. The selection includes HSS, cobalt, solid carbide, carbide-tipped and PCD options, depending on the family. Check the tool substrate and construction on the individual product listing.
- Are center drills and spotting drills interchangeable?
- They are separate tool families with different geometries. Select the center drill form specified for a center hole or the spotting drill geometry required for a spotting operation. Compare the point angle, diameter and application guidance before substituting one for the other.
- How do I choose a countersink or counterbore?
- Match the tool to the required recess. A countersink creates an angled recess; a counterbore produces a flat-bottom recess. Check the fastener specification, angle where applicable, cutting diameter and pilot dimensions.
- What dimensions matter for keyseat cutters and slitting saws?
- Compare cutter width, outside diameter and available cutting depth, then check shank or arbor-hole size, neck clearance, tooth configuration and cutting direction. Tools with the same diameter can produce different features or require different mounting arrangements.
- How can I check KEO stock and place an order?
- Search by the full manufacturer part number or use the linked categories. Confirm the dimensions, tool material and coating, then review local or factory stock information shown for the item. Availability depends on the exact part and quantity. You can also use product links in the interactive ARCH catalog to shop online at Suncoast Precision Tools.
