Key Features

Built to Last: Made of high-strength 4241 high-speed steel with titanium coating, this product has high hardness, strong rust-repellent performance, excellent processing stability, and longer service life.

Multi-size Compatibility: The set contains 4 different sizes of tools, with shank diameters corresponding to 6mm, 8mm, 10mm and 12mm, which can accurately match the processing of various hole diameters of 2-5mm, 5-10mm, 10-15mm and 15-20mm, and comprehensively cover the range of daily processing sizes.

Chip Removal Design: The groove-type removal structure enables rapid chip discharge, preventing chip clogging of the workpiece. This makes for a stable and safe machining process.

Exceptional Performance: Featuring a precision 90° chamfered tip design, this tool delivers sharp, accurate countersinking for circular or tapered holes in workpieces, as well as edge chamfering. It produces smooth cuts with clean machined surfaces.

Easy to Use: Designed for use with bench drills, the unique slotted tapered surface enables machining without vibration, effectively preventing wobble from compromising chamfering results. You can simply maintain the drill's lowest speed and apply light pressure to achieve premium machining.

Details

Well-made Cutting Edges: The cutting edge is hardened and honed to provide excellent sharpness, smooth cutting without jamming, and improve efficiency.

Sleek and Round Edges: They further enhance the product's texture and usage safety.

Application

This set is widely applicable to various materials, including timber, fibreboard, chipboard, plywood, plastics, aluminium sheets (hardness < 28 degrees), metals with hardness < 25 degrees, and thin iron sheets. It is suitable for diverse scenarios such as domestic DIY projects, repair shops, general construction/engineering work, and small-scale workshops.

Notes

• Please check the size carefully before ordering.
• Please note that hand drills are not recommended, as they may lead to deviations in machining accuracy.
• Please allow the slight color difference caused by the shooting light and the 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
