Some jobs require specialized miniature end mills to accomplish specific tasks such as working with jewelry, clocks or models.
MINIATURE 2 FLUTE SINGLE END MILLS
2 Flute - Regular Length page 264
High Speed Steel Miniature 2 Flute Single End Mills are designed with a common 3/16" shank to provide rigidity when doing small diameter slot milling, engraving, pocket milling, and similar operations requiring fine detail work.
MINIATURE 4 FLUTE SINGLE END MILLS
4 Flute - Regular Length page 264
High Speed Steel Miniature 4 Flute Single End Mills are designed with a common 3/16" solid center shank to provide rigidity when doing small diameter milling of slots and pockets, edge planing, and finishing surfaces where plunge cutting is not required. End mills with 4 flutes are stronger and more rigid than 2 flute end mills and produces a finer milled finish.
MINIATURE 2 FLUTE BALL NOSE SINGLE END MILLS
2 Flute - Single End - Regular Length page 264
High Speed Steel Regular Length Miniature 2 Flute Ball Nose Single End Mills are designed with a common 3/16" solid center shank to provide rigidity for doing small diameter contour milling, convex slots, round bottom holes, engraving and other similar milling operations requiring fine detail work.

2 Flute - Double End - Regular Length page 264
High Speed Steel Regular Length Miniature 2 Flute Ball Nose Double End Mills are designed with a common 3/16" solid center shank to provide rigidity for doing small diameter contour milling, convex slots, round bottom holes, engraving and other similar milling operations requiring fine detail work. Double end mills will cut twice as long as single end mills and when one end wears out, it can be quickly reversed in the collet to reduce changeover time, overall costs and inventory.
MINIATURE 2 FLUTE DOUBLE END MILLS - CENTER CUTTING
HIGH SPEED STEEL
2 Flute - Regular Length - High Speed Steel page 265
High Speed Steel Regular Length Miniature 2 Flute Double End Mills are designed with a common 3/16" solid center shank to provide rigidity when doing small diameter slot milling, engraving, pocket milling, and other similar milling operations requiring fine detail work. Double end mills will cut twice as long as single end mills and when one end wears out, it can be quickly reversed in the collet to reduce changeover time, overall costs and inventory.

2 Flute - Long Length - High Speed Steel page 265
High Speed Steel Long Length Miniature 2 Flute Double End Mills are designed with a common 3/16" solid center shank to provide rigidity when doing small diameter slot milling, engraving, pocket milling, and other similar milling operations requiring fine detail work where extra reach is required. Double end mills will cut twice as long as single end mills and when one end wears out, it can be quickly reversed in the collet to reduce changeover time, overall costs and inventory.

SOLID CARBIDE
2 Flute - Stub Length - Solid Carbide page 278
Micrograin Stub Length Solid Carbide 2 Flute Miniature Double End Mills are designed with a common 1/8" or 3/16" solid center shank to provide extra rigidity when doing small diameter slot milling, engraving, pocket milling, and other similar milling operations requiring extra fine detail work. The stub length flutes are stronger and more rigid than regular length flutes and are used to machine tough work hardening metals and abrasive materials. Double end mills will cut twice as long as single mills and when one end wears out, it can quickly be reversed in the collet to reduce changeover time, overall costs, and inventory.
MINIATURE 4 FLUTE DOUBLE END MILLS - NON-CENTER CUTTING
HIGH SPEED STEEL
4 Flute - Regular Length - High Speed Steel page 265
High Speed Steel Regular Length Miniature 4 Flute Double End Mills are designed with a common 3/16" solid center shank to provide rigidity when doing small diameter milling of slots and pockets, edge planing, and finishing surfaces where plunge cutting is not required. End mills with 4 flutes are stronger and more rigid than 2 flute end mills and produces a finer milled finish. Double end mills will cut twice as long as single end mills and when one end wears out, it can be quickly reversed in the collet to reduce changeover time, overall costs and inventory.

4 Flute - Long Length - High Speed Steel page 265
High Speed Steel Long Flute Miniature 4 Flute Double End Mills are designed with a common 3/16" solid center shank to provide rigidity when doing small diameter deep milling of slots and pockets, edge planing, and finishing surfaces where extra reach is required. End mills with 4 flutes are stronger and more rigid than 2 flute end mills and produces a finer milled finish. Double end mills will cut twice as long as single end mills and when one end wears out, it can be quickly reversed in the collet to reduce changeover time, overall costs and inventory.

SOLID CARBIDE
4 Flute - Stub Length - Solid Carbide page 278
Micrograin Stub Length Solid Carbide 4 Flute Miniature Double End Mills are designed with a common 1/8" or 3/16" solid center shank to provide extra rigidity when doing small diameter milling of slots and pockets, edge planing, and finishing services. They are center cutting and can plunge to depth to start milling and slotting. The 4 flute design is stronger and more rigid than the 2 flute design and produces a finer milled finish. They are used to machine tough work hardening metals and abrasive materials. Double end mills will cut twice as long as single mills and when one end wears out, it can quickly be reversed in the collet to reduce changeover time, overall costs, and inventory.
