Centre drill DIN 333 Form A, Ø 1.25 mm — solid carbide, 60° tip (TECWERK)

The centre drill DIN 333 Form A, Ø 1.25 mm is a solid‑carbide centre drill designed to produce precise centring holes to DIN 332 with a 60° countersink, suited to demanding workshop and light production environments

• Solid‑carbide (VHM) construction
• DIN 333 Form A with 60° countersink
• Right‑hand cutting for clean centring
• Compatible with steels, castings and plastics

High‑precision centring for consistent production

The short, rigid geometry of this centre drill delivers reliable alignment and repeatable results in serial work. The solid‑carbide body provides high stiffness and thermal stability, which reduces runout and preserves concentricity during drilling. The 60° countersink corresponds to standard centre‑hole profiles per DIN 332, ensuring compatibility with conventional lathes and centres; this reduces set‑up time and the need for secondary operations. The design therefore supports process reliability and predictable part fitment.

Broad material range with clear performance data

Selected for multi‑material use, the tool handles high‑strength steels, cast components and a variety of non‑ferrous and advanced polymers without frequent tool changes. The specification explicitly lists suitability for cast steel, grey and hard cast irons, manganese‑hard steels, CrNi stainless grades, light metals and fibre‑reinforced plastics, as well as other duroplastics. For guidance under load, the recommended feed in steel up to 800 N is 0.08 mm/rev, providing a practical baseline for machining parameters and helping to balance surface finish with tool life.

Why the DIN 333 Form A geometry matters

Form A centring drills combine a drilling pilot with a countersink in a compact tool body to create an accurate, burr‑free centre hole. The inclusion of a 60° tip produces the standard seating angle for centres and tailstocks, improving concentric clamping and reducing wobble during turning or re‑boring. This version is supplied without protective countersink, which means it is optimised to cut the defined centre profile directly; the right‑hand cutting flutes ensure clean evacuation of chips and stable cutting action on through‑holes or short pre‑drills.

Practical workshop benefits and handling notes

The tool is suitable for both CNC and manual operations where fast, precise centring is required. The carbides’ wear properties and thermal resistance support higher cutting speeds and reduce regrinding frequency, translating into lower downtime and lower per‑part cost over time. For best results, match spindle speed and feed to the listed guideline and ensure secure clamping to exploit the drill’s rigidity. The combination of standard geometry and durable material makes it a practical choice where consistent centring and minimal rework are priorities.

FAQ

What materials can this centre drill machine reliably cut? The centre drill is specified for a broad range: high‑strength steels, cast steel, grey and hard cast irons, manganese‑hard steels, CrNi stainless steels, light and non‑ferrous metals, fibre‑reinforced plastics and other duroplastics.

What does the 60° countersink achieve in practice? A 60° countersink creates the standard centre seating profile for conventional centres and tailstocks, improving concentric clamping and reducing runout during turning and drilling operations.

How should feed and speed be chosen for steel applications? Use the guideline feed of 0.08 mm/rev for steel under 800 N as a starting point; adjust spindle speed and chip evacuation based on material hardness and machine rigidity to extend tool life.

Is this tool suitable for both CNC and manual workshop use? Yes, the rigid solid‑carbide construction and Form A geometry make it suitable for both CNC and manual operations where precise centring is required.

What indicates the product uniquely on order lists? Order by SKU 2000861989NW to ensure the correct TECWERK centre drill (DIN 333 Form A, Ø 1.25 mm) is supplied.
