Compatible Materials by Cut Type

The DRILLCO 7000 series distinguishes itself through its solid carbide head construction and brazed shank design, which together deliver superior concentricity and reduced vibration compared to burrs with mechanically attached heads. The optimized flute geometry is engineered to balance fast stock removal with a fine finish, making these sets suitable for both rough material removal and finishing work without changing tools.

Key Features & Benefits

Double Cut Tooth Design

The double cut tooth pattern provides aggressive material removal across ferrous and non-ferrous metals. This design allows contractors to work faster through tough materials including stainless steel, Inconel, and hardened steels up to 60 Rc.

Solid Carbide Head Construction

Manufactured from premium-grade tungsten carbide, the solid carbide head delivers premium performance and maintains cutting edge integrity longer than lesser materials. This construction is suited to demanding metalworking environments where tool longevity directly impacts productivity.

Brazed Shank for Concentricity and Reduced Vibration

The brazed shank connection ensures perfect concentricity between the cutting head and shank, minimizing runout during operation. Reduced vibration translates to better operator control, improved surface finish, and less wear on the grinder.

Optimal Flute Geometry

The flute geometry is engineered for fast removal and fine finish in a single tool, reducing the need to switch between roughing and finishing burrs. This makes the set especially efficient for complex geometries and tight-space applications.

Broad Shape Selection

The 7000 series is available in twelve USCTI burr shapes — including cylindrical, ball, tree, flame, cone, conical, egg, and inverted cone — giving contractors the right profile for virtually any contour, cavity, or edge geometry they encounter on the job.

Multiple Series and Shank Options

Burrs are available in standard lengths, 6" long series, and miniature sizes for pencil grinders, with 1/4" and 1/8" shank diameters available. This range ensures compatibility with a wide variety of die grinders and point grinders used in the field.

Common Applications

Deburring

Removes sharp burrs and edges left after machining, cutting, or punching operations on metal workpieces, improving part safety and fit.

Weld Removal

Efficiently grinds down weld beads and spatter on fabricated assemblies, including stainless steel and carbon steel weldments, to achieve flush, clean surfaces.

Material Removal in Tight Spaces

The variety of burr shapes and the availability of miniature sizes for pencil grinders allow access to confined areas, ports, and recesses where larger abrasive tools cannot reach.

Material Removal on Complex Geometries

Ball, egg, flame, tree, and conical profiles conform to curved and contoured surfaces, enabling precise stock removal on complex part geometries without damaging surrounding areas.

Frequently Asked Questions

Q: What tooth design does the 70S001DC use, and what is it best suited for?
A: The 70S001DC uses a double cut tooth design, which is engineered for aggressive material removal. Double cut burrs are recommended for ferrous metals including carbon steel, stainless steel, Inconel, titanium, and hardened steels up to 60 Rc, as well as materials such as fiberglass, hard rubber, and plastics.

Q: What is the difference between the double cut and single cut (Magnum) sets?
A: The double cut sets (item numbers ending in DC) use a cross-cut tooth pattern for aggressive stock removal on ferrous metals and hard alloys. The single cut Magnum sets (item numbers ending in SC) use a single-direction flute pattern. An aluminum/non-ferrous cut Magnum set (70S010NF) is also available, specifically designed for aluminum, copper, brass, zinc, magnesium, carbon fiber, and other non-ferrous materials.

Q: What is the maximum safe operating speed for these burrs?
A: Maximum RPM depends on burr diameter. For standard-length burrs: 1/4" — 70,000 RPM; 5/16" — 68,000 RPM; 3/8" — 66,000 RPM; 7/16" — 58,000 RPM; 1/2" — 50,000 RPM; 5/8" — 40,000 RPM. For 6" long burrs, maximum speeds are halved (e.g., 1/4" — 35,000 RPM). For safety reasons, never use 6" tungsten carbide burrs below 20,000 RPM.

Q: What burr shapes are available in the 7000 series?
A: The 7000 series is available in twelve USCTI shapes: Cylindrical (SA), Cylindrical End Cut (SB), Cylindrical Round Nose (SC), Ball (SD), Egg (SE), Tree (SF), Tapered (SG), Flame (SH), Cone 90° (SK), Cone (SL), Conical (SM), and Inverted Cone (SN).

Q: What shank sizes are available, and are these compatible with pencil grinders?
A: The 7000 series is available with 1/4" shank diameter for standard die grinders and 1/8" shank diameter for use in pencil grinders (miniature sizes). A 6" long series with 1/4" shank is also available for extended-reach applications.

Q: Why does the brazed shank construction matter for job site performance?
A: The brazed shank ensures perfect concentricity between the carbide cutting head and the shank. This minimizes runout during operation, which reduces vibration, gives the operator better control, and helps protect the grinder from unnecessary wear — all of which contribute to longer tool and equipment life.
