Cobalt-Containing High Speed Steel Spot Drill with Titanium Coating, Straight Shank, External Cooling, 3-20mm Sizes, M3-M20X90 Colour Options for Precision Hole Centring
Cobalt-Containing Titanium Spot Drill with Straight Shank for Metal Hole Centring

This cobalt-containing high speed steel spot drill is designed for starting holes accurately on metalwork before switching to a full drill bit. The straight shank allows it to sit in standard tool holding setups, while the titanium plating adds a stated surface treatment that supports the tool during repeated drilling. External cooling is specified, which helps manage the cutting area during operation. The drill is offered in specifications 3, 4, 5, 6, 8, 10, 12, 16, 18 and 20, with colour options running from M3X90 to M20X90. A maximum depth of cut of 20 and blade size 20 are also listed. Each order contains one spot drill, so you can choose the exact size and colour option required for your task.
Features and Construction

The construction details centre on the combination of cobalt-containing high speed steel, titanium plating, a straight shank and external cooling. These are practical tool features rather than decorative additions, and they relate directly to how the spot drill is held, cooled and used during metal drilling tasks.
Material and Build
The drill is made from high speed steel containing cobalt, with cobalt also listed separately as a material. This places it in the category of cobalt-bearing cutting tools, which is relevant when the work involves starting holes in metal. The titanium plated finish is a stated surface treatment. Together, these details describe a tool built for drilling rather than general-purpose use. The straight shank keeps the mounting method simple and compatible with common tool holders.
Size and Practical Fit
Specifications listed are 3, 4, 5, 6, 8, 10, 12, 16, 18 and 20. Colour options are M3X90, M4X90, M5X90, M6X90, M8X90, M10X90, M12X90, M14X90, M16X90, M18X90 and M20X90. The maximum depth of cut is 20 and the blade size is 20. These figures allow you to match the spot drill to the scale of the hole or centring point you are preparing, from smaller work through to larger diameters.
Uses and Placement

This spot drill is intended for creating a controlled starting point before drilling continues. That makes it relevant to metalworking tasks where drill wander needs to be reduced and the entry point needs to be defined. It can also be kept with other workshop tooling for routine use.
Event or Professional Use
In a workshop or professional setting, a spot drill helps prepare a hole location before the main drilling operation. The straight shank allows it to be fitted into suitable tool holders, and the external cooling type is specified for operation. The listed sizes cover a range of common drilling needs, while the M-series colour options make it easier to identify the required variant.
Everyday Home Use
For home workshop use, this spot drill offers a way to start holes more accurately when working with metal components. It is not a general-purpose drill for every material, and the source information does not state suitability beyond the listed material and construction. Select the relevant specification and colour option, fit it securely and use it with external cooling as stated.
Benefits and Buying Value

The buying value comes from having a cobalt-containing, titanium plated spot drill in the specific size and colour option you need. The straight shank and external cooling are stated features, and the range of specifications allows for matching to different tasks without relying on unsupported claims.
Reuse and Low Maintenance
The tool is supplied as one spot drill, so care centres on keeping it clean and storing it safely between uses. The source text does not provide detailed maintenance instructions. Low-risk handling means keeping the cutting edge protected, avoiding impact damage and using the drill within the stated maximum depth of cut of 20.
Why Choose This Product
Choose this spot drill when you need a cobalt-containing high speed steel tool with titanium plating, a straight shank and external cooling in a defined size. The specifications from 3 to 20 and the colour options from M3X90 to M20X90 give clear choices. Each pack contains one spot drill, making the selection specific to the task at hand.
