High speed steel and cobalt drills for applications requiring durable and adaptable geometry choices.
Drills and cutting tools matched to the application
HADI Technologies presents Lidsters Paragon cutting and drilling solutions in Israel, including HSS, HSCO and carbide drills, carbide tipped drills and reamers. Standard and drawing based tools can be evaluated.
Lidster Paragon Tool Co Ltd is a British manufacturer of drills and cutting tools founded in London in 1964 and now operating from a purpose built factory in Killamarsh near Sheffield. The company states that it employs more than 40 people and makes HSS, HSCO and carbide tools, with many products built to customer drawings or specifications.
Its range covers solid carbide, carbide tipped and HSS tools, as well as reamers and specialist cutters. The company serves aerospace, automotive, structural steel, medical, composites, marine, oil and gas and other sectors. CNC equipment, small batch capability, volume production and surface treatments support selection by material, geometry, depth and cutting rate. Tool length, coolant and machine interface also affect the result. Define the complete cutting environment rather than the requested drill diameter alone.

Selection requires workpiece material, hole diameter and depth, machine, cutting speed, coolant and tolerance. For a special tool, include an existing marking, drawing and cutting geometry.
Hadi can organize the cutting data and check a stock or drawing-based Lidsters tool. Share material and hole data for matching and a quotation.
The choice depends on workpiece material, machine rigidity, cutting speed, hole depth and vibration risk. HSS and HSCO offer flexibility under changing conditions, while solid carbide suits higher stiffness and speed when the machine is stable enough.
A reamer improves the size and finish of an existing hole, so it is not a replacement for the initial drilling operation. Leave the correct allowance, align the tool and part, and select geometry and tool material for the workpiece and required tolerance.
Specify workpiece material, diameter and depth, tolerance, hole geometry, machine type, coolant, speed and feed. A drawing plus existing wear or failure data is useful because tool length, coating and machine connection can affect performance as much as cutting diameter.
Start with the material structure, fibre or layer direction, finish requirement and chip evacuation method. Select tool material, geometry and surface treatment, then tune cutting parameters while checking delamination, heat and wear on a production sample.
