NUMBER AND LETTER PUNCHES FOR METAL WORK

HIGH QUALITY, LOW COST NUMBER AND LETTER PUNCHES
Robinson International Pty Ltd supply professional quality number and letter punches.

• Made from S55C carbon steel correctly hardened and tempered to hardness HRC 58-62.
• Most are available with “tail end tempering”.
• Softer hit end means no chance of flying steel chips
• All punches are abrasive blast finish which ensures rust resistance.
• Packed in strong polypropylene boxes marked with size.
• These punches will keep on marking hit after hit!

The triangular support design of the marking face of these punches, coupled with expert production eliminates the possibility of the image cutting edge crushing or chipping when cutting hardened metals

GAUGES

Various types of gauges are used for accurate measuring and testing.
CENTERING GAUGES are specially designed indicators for internal and external centering of jobs on machine tools.
• Can be used with machine spindle turning to allow speedy set up.
• Can be used vertically or horizontally
• Available with metric or inch reading

CENTERING GAUGE SET

RADIUS GAUGES come in various styles and are used to measure the radius of inner and outer surfaces of an object.

• Both external and internal radius on each leaf.

Inch radius sizes 1/32-17/64 and 9/32-33/64

Metric radius sizes 0.75mm-5mm and 5.5mm -13mm

• Separate leaves for external and internal radii.

Sizes: 1mm-7mm; 7.5mm-15mm;15.5mm-25mm

• Separate gauges for each radius.

Five measuring positions on each gauge.

Come in both metric and inch radii.

SMALL HOLE GAUGE
4pce set 1/8″-1/2″ capacity
These are used to measure the diameter of a bore by inserting the gauge into the bore and adjusting till light pressure felt. The gauge is then measured with a caliper or micrometer.

SURFACE ROUGHNESS GAUGES
• The surface roughness gauge set is a reliable and easy way for checking, identifying and specifying the degree of roughness of machined parts.
• The set contains thirty steel specimens of six machining methods: flat-lapping, reaming, grinding, horizontal milling, vertical milling and turning.
• Each specimen measures 7/8″ length x 3/8″ width and are calibrated in micro inch and micro meters.
• A chart giving metric and imperial equivalents for each surface roughness measurement is included in the set.

SURFACE ROUGHNESS GAUGES

SURFACE ROUGHNESS GAUGES

SURFACE GAUGES
• Fine ground steel base
• Fine adjustment screws
• Available 4″/7″ and 9″/12″
Used to measure the height of objects in metalwork. The pointer acts as a scriber for marking out work pieces.

SURFACE GAUGES

MICROMETER CHECK SET
The components that the set can check are length, flatness and parallelism of measuring faces. With the addition of optical flats the ¼ turn parallelism can also be checked.
• The 6425S MICROMETER CHECK SET can check the accuracy of micrometers from 0-25mm capacity up to 200mm capacity.

• It can also be used for checking vernier calipers to the same capacity.

• The set is based on the requirements of ISO3611-2010 (AS2102 amended) with the inclusion of 50, 75 and 100 mm gauges to allow larger capacity.

All sets are packed in secure, attractive protective cases.

GO/NOGO SCREW THREAD PLUG AND RING GAUGES

Used for checking, calibrating or setting of gauges.

SCREW THREAD GAUGES

• PLUG GAUGES from 1.6m to 355mm

• RING GAUGES from 2.00mm to 285mm

Available are gauges made to any tolerance grade in almost every thread type from any country or standard.

ALL GAUGES ARE SUPPLIED WITH TRACEABLE CERTIFICATES ACCEPTED UNDER ILAC AND MRA AGREEMENTS

• Gauge members are correctly heat treated and stabilised and have uniformly distributed carbides in a matrix of tempered martensite.

• Gauge members are size selected to maximum metal condition as this gives longer wear life.

• These features are only available from a maker with the highest precision measuring and calibration equipment and with independently assessed very small uncertainty of measurement.

PLAIN PLUG GAUGES
These are available in steel or with tungsten carbide Go member in sizes starting from 0.5mm upwards.

AEROCUT BROACH ARTICLE

Broaching is a machining process that uses a toothed tool, a broach, to remove material.

AEROCUT KEYWAY broaches quickly, easily and economically produce keyways in any sort of job.

An important feature of AEROCUT broaches is they are TiN coated at no extra cost.

Titanium Nitride (TiN) is applied as a thin coating to harden and protect cutting surfaces.

AEROCUT push-type KEYWAY broaches come in imperial and metric sizes and are supplied complete with shims.

Imperial (inch) sizes range from 1/16” up to 1”

Metric sizes range from 2mm up to 25mm

AEROCUT BROACH AND SHIMS

AEROCUT BROACH AND SHIMS

Collared or plain bushes are available for all bore sizes.

SQUARE BROACHES

Imperial (inch) sizes range from 1/8” to 1”

Metric sizes range from 4mm to 25mm

HEXAGONAL BROACHES

Imperial (inch) sizes from 1/8” to 1”

Metric sizes from 4mm to 25mm

KEYWAY BROACH SETS contain the most common keyway metric or imperial (inch) broaches and a range of bushes packed in varnished wooden boxes.
