Hinge Drill Bit Compatibility With Hettich Blue Max
Will these bits fit my Hettich Blue Max machine?
Yes, these are genuine Hettich replacement bits designed specifically for the Blue Max and many other industry-standard hinge boring machines. They typically feature a 10mm cylindrical shank with a flat clamping surface (whistle notch) or a screw thread, depending on your specific machine's chuck. Please check your machine manual; if it takes standard 10mm shank bits, these are the correct fit.
Choosing The Correct 35mm Hinge Cup Drill Bit
Do I need a specific bit for the 35mm hinge cup?
Yes. The standard Hettich hinge cup hole is 35mm. You will need the large 35mm cylinder boring bit for the main hole. If your machine also drills the smaller holes for the press-in dowels (the "Ecomat" or "Sensys" pattern), you will likely need two 10mm or 8mm bits for the side spindles, depending on the specific hinge pattern you are using.
Drilling Melamine And Chipboard With Hinge Bits
Are these suitable for drilling melamine and chipboard?
Absolutely. These bits are TCT (Tungsten Carbide Tipped). Standard High-Speed Steel (HSS) bits will blunt almost immediately on the abrasive glues found in particle board and MDF. Carbide tips are essential for maintaining a sharp edge and producing clean holes in man-made boards over thousands of cycles.
Using Hinge Drill Bits With Drill Presses
I'm a hobbyist with a drill press. Can I use these?
Yes, provided your drill press chuck can hold a 10mm shank securely. These bits produce an exceptionally flat-bottomed hole, which is perfect for concealed hinges where the cup depth must be precise (usually 11mm-13mm). Just ensure you clamp your workpiece down firmly, as the large 35mm bit can grab the timber if it's loose.
Preventing Cabinet Door Tear Out When Drilling
Will this tear out the white face of my cupboard doors?
These bits feature scribing spurs (precisely ground tips on the outer circumference). These spurs cut the melamine fibers before the main cutter removes the waste, ensuring a crisp, chip-free edge on the hole entry. If you notice chipping, it is a sign the spurs are dull and the bit needs replacing.
Sharpening Hinge Drill Bits
Can these bits be sharpened?
High-quality TCT bits can be sharpened by a professional saw doctor using diamond wheels. However, given the relatively low cost of replacement bits versus the cost of professional sharpening (and the loss of diameter/geometry), most trade users treat them as consumables and replace them when they start to dull.
