Series J100 - Inch
General purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite. Point angle: 118°, helix angle: normal, web thickness: standard, relief angle: 10°-20°, tolerance of diameter: h8, tolerance of shank: f11. Manufactured to BS 328/DIN338RN.

Bright Finish
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.

SwissBurr hand deburring tools are a fast effective and efficient way of deburring holes, slots and edges. Swiss Burr is a totally modular system of interchangeable handles, holders and blades designed to cover all applications. A choice of HSS or carbide blades, countersinks and scrapers are available to suit your specific application. Swiss Burr blades are also interchangeable with commonly available brands including Kennedy, Noga, Ruko, Seco, Snap-Tap and Stellram.

F12 - HSS countersink for hole edges up to 12mm dia.
F20 - HSS countersink for hole edges up to 20mm dia.
F30 - HSS countersink for hole edges up to 30mm dia.

Oval Shape.
All sizes are nominal with a 6mm shank unless other wise stated.

Cut 9 - Chipbreaker
Chipbreaker fast stock removal for improved control and reduced chips for use on hard materials, i.e. steel alloy 50RC, 60RC, carbon and cast iron.

Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel etc.
up to HRC65 hardness.

Please note:
• Work piece 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 and high revolutions '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.
