Series J100 - Metric general purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite.

Features and Benefits
• High speed steel construction with bright finish for increased toughness
• Supplied in the as-ground condition for use with non ferrous materials

Standards
• Manufactured to BS 328/DIN338RN

Notes
• Drills with a bright finish are supplied in the as-ground condition and such tools are used generally in the machining of non-ferrous materials.

The J100 Series are general purpose HSS straight shank drills with a black oxide finish. Ideal for applications involving steel (including cast steel) cast iron (including malleable cast iron) as well as nickel, brass aluminium alloys and graphite. Their 118° point allows for precise hole alignment and reliable cutting performance whilst the black oxide coating helps reduce heat by retaining coolant on the tool surface. The coating also helps reduce the risk of the tool staining.

Features and Benefits
• High speed steel construction for increased tool durability
• Point angle of 118° for precise holemaking and precision cutting
• Black oxide coating helps aid chip flow, reduce heat and prevent staining
• Ideal for applications involving steel, iron, nickel, brass, aluminium alloy and graphite

Typical Applications
• Cutting and drilling
• Ferrous materials
• Steel
• Iron
• Nickel
• Brass
• Aluminium alloy
• Graphite

Notes
• Available in sizes 0.25mm -20.00mm

Standards
• Manufactured to BS 328/DIN338RN

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.
