Countersink & Combi
Tools
Combination drill-countersink tools that create a hole and its countersunk recess in a single operation. Drill and chamfer in one pass — no tool changes, no realignment, just flush-fit hardware every time.
How It Works
A single tool performing two operations — here's the engineering behind the one-pass drill and chamfer.
Why Combi Tools
Two operations, one tool. Every feature engineered for speed and precision.
Single-Pass Efficiency
Drill the through-hole and create the countersunk recess in one operation, eliminating tool changes and reducing cycle time by up to 50%.
Precise Angle Matching
Countersink geometry precisely matches standard 90° and 120° hardware angles, ensuring perfect flush fit for flat-head screws and bolts.
Dedicated Countersink Option
Standalone countersink tools available for chamfering existing holes, deburring edges, or creating lead-in chamfers without drilling.
Premium Carbide Construction
Both drill and countersink portions use premium carbide, available in Standard, Premium, and Ultra-Premium quality grades.
50% Faster Cycle Time
By combining drilling and countersinking into a single pass, you eliminate tool change downtime and reduce overall cycle time by up to half.

Where It Matters
Every flush-mount hardware installation benefits from the combi approach.
Shower Enclosures
Hinge Mounting
Shower enclosure hinges require flush-mount screws that sit perfectly within the glass surface. Protruding hardware creates water traps, aesthetic flaws, and potential safety hazards. Combi tools drill the hinge mounting hole and create the countersunk recess in one pass, ensuring each hinge sits flush and functions reliably.

Common Questions
Everything you need to know about countersink and combi tools.
Use combination tools when you need flush-mount hardware and want to minimize cycle time — they drill and countersink in one pass. Use separate tools when you need flexibility to vary the countersink angle, depth, or when countersinking existing holes without drilling.
Standard angles are 90° (for most flat-head screws and bolts) and 120° (for some specialized fasteners). Custom angles are available on request. The angle must match your hardware specification for proper flush fit.
Yes. Dedicated countersink tools (without the drill portion) are designed specifically for chamfering existing holes. They're available in the same diameter range and quality grades as our drill bits.
The recess depth should match the head height of your hardware — typically 2–4mm for standard flat-head screws. The goal is a perfectly flush surface where the hardware head sits level with or slightly below the glass surface.
