Plain Shank
Spiral flute, 3 flute. Medium duty. Used for milling of pre-drilled holes to allow bolt or cap head screws to lie flush with the component surface. Manufactured to manufacturers standard

These carbide burrs are designed for cylindrical end cutting of low feed, high speed materials. Available in a variety of sizes with varying cut capabilities.

Features and Benefits
• Manufactured from durable carbide for tool longevity
• Rapid cut (Cut 3) burrs are suited for use on softer non-ferrous and plastic materials
• Chipbreaker (Cut 9) burrs are suited for use on cast iron, carbon steel, alloy steel 50RC and 60RC
• Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel up to HRC65 hardness
• Ideal for light stock removal at high rpms

Typical Applications
• Deburring

Notes
• Not suitable for milling large amounts of material
• Always ensure that at least 70% of the shank length is clamped by the collet or chuck of the tool being used
• Always ensure that the tool is rated to the recommended operating speed of the burr

SPKN Milling Inserts

Square Insert

Insert Grade QP40
(P40) Uncoated. For rough medium and finish milling of tough Steels and Stainless Steels including interrupted cutting.

Senator jobber drills are roll forged from HSS, ensuring uninterrupted grain structure. This provides exceptional strength and durability. Tips are ground for effective cutting. Suitable for drilling wood, plastic, carbon and plain steels where the cutting efficiency of ground flute is not required.

Features and Benefits
• HSS construction for increased rigidity
• Ground tips for effective cutting performance
• Ideal for use on a range of substrates including wood, plastic, carbon and steels

Standards
• Manufactured to DIN 338 Type N
