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.

The Kennedy range of HSS-Co heavy duty straight shank jobber drills provide durable and reliable cutting performance at high temperatures and speeds thanks to the addition of 5% cobalt to their alloys. Their toughness and heat resistance allows them to to drill steels with tensile strength up to 1,400 N/mm², very hard bronze, stainless steels as well as heat and acid resistant steels.

Long lasting the cutting edges retain their sharpness for longer periods, maximising performance and productivity, whilst also being resistant to corrosion.

Features and Benefits
• Made with a 5% cobalt alloy for optimal performance at high speeds and temperatures
• Allows for optimal cutting of metals up to a tensile strength up to 1,400 N/mm²
• 135° point angle for precise hole making and efficient cutting
• For applications including steel, bronze, stainless and acid resistant steels
• Extended lifespan on cutting edge, required less sharpening over time
• Excellent corrosion resistance extends the lifespan of the tool

Standards
• Manufacturing Standard: BS 328, DIN 338B

Typical Applications
• Cutting and drilling
• Hard metals
• Stainless steel
• Bronze

Notes
• Available in sizes 1-13mm

Cut 9 conical carbide burrs feature a cut-9 chipbreaker for fast stock removal, improved control and reduced chips. Ideally suited to hard materials such as steel alloy 50RC, 60RC, carbon and cast iron.

Features and Benefits
• Manufactured from a tough carbide substrate for greater tool hardness
• Cut-9 chipbreaker increases stock removal and chip control
• Ideal for use on hard materials such as steel alloys and more

Typical Applications
• Deburring
• Polishing
• Cast iron
• Cast steel
• Carbon steel
• Alloy steel
• Stainless steel
• Materials up to HRC65 hardness

Notes
• Workpiece and tools should always be steady and well supported
• Carbide burrs are not suitable for 'milling' large amounts of material, they are for light stock removal at high rpm's 'LOW FEED - HIGH SPEED'.
• 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.
