Guhring publishes new deep hole drilling catalogueBirmingham-based cutting tool manufacturer Guhring has published a new 250-plus deep hole drilling catalogue which is dedicated to its new, expanded and existing deep hole drilling product lines that are all available ‘off-the-shelf’ as standard.

The information-packed catalogue introduces deep hole drilling lines from 0.9mm to 52mm diameter with overall drill lengths of beyond 3m in variants that include solid carbide gun drills, brazed gun drills, modular drills, spiral fluted solid carbide and HSS drills as well as pilot drills and accessories.

Featured in the publication are the EB100 and EB100M series of deep hole drills. As the smallest and most robust of the Guhring lines, the EB100 is available from 0.9 to 16mm diameter with an 80xD that takes the flute length to 580mm.

Suitable for most material types, this brazed solid carbide single fluted gun drill is the perfect complement to the EB100M series. The EB100M is an ultra-precise variant for drilling particularly tight tolerance holes, and it offers an MQL shank end to further enhance performance.

Both drills are complemented by the EB80 and EB80 XXL brazed single-fluted gun drills which have been expanded with new forms and coatings added to the conventional series that covers hole diameters from 2 to 40mm with total drill lengths up to 3.6m.

The ZB80 series that was previously introduced specifically for cast-iron drilling has also been expanded with diameter ranges from 6 to 30mm and overall lengths up to 1m for this two-fluted brazed carbide specialist range.

GuhringMeanwhile, the Guhring EB800 single-fluted gun drills with interchangeable inserts and guide pads have now been expanded yet further with more new insert grades, coatings and geometries to maximise hole-making performance.

With each different drill body covering a 0.5mm diameter in the 12 to 52mm scope of the series, Guhring has introduced expanded drill dimensions with new EB800 insert grades and coatings that are complemented by matching guide pad and inner insert upgrades.

Completing the drilling line-up is the HSS and solid carbide spiral-fluted deep hole drills and the pilot drilling tools. With the pilot process being so critical to the precision and concentricity of the hole, Guhring presents a variety of options that include solid carbide and HSS stub-length drills, indexable drills, centre cutting end-mills and piloting end mills – all designated to maximise precision and performance.

The publication also contains all the accessories and extra equipment required to help engineers generate the perfect hole. This comprehensive range of additional extras includes everything from drill bushes, steady rest bushes, moulded steady rest bushes, sealing disks and plugs, adjustment screws, torque wrench sets and even drill grinding and resharpening equipment.

Finally, the catalogue also contains a technical section with tables, charts and useful data for maximising machining performance. It is the definitive guide for deep hole drilling applications as it includes information on drilling processes, pilot holes and drill bushes, coolant and lubrication data, head forms, re-grinding and re-tipping, application recommendations and much more.
