Wera Bit-Check 30 Diamond 1 — 30-Piece Diamond-Coated Bit Set
30 PiecesDiamond-Coated TipsBiTorsion ZoneRapidaptor Holder Included
Bit-Check 30 Diamond 1 is a working assortment rather than a display set: twenty-nine diamond-coated BiTorsion bits weighted towards the sizes that wear out first — four PH 2, four PZ 2, three TX 20 and three TX 25 — plus a 889/4/1 K Rapidaptor universal holder that counts as the thirtieth piece. The BDC diamond coating puts microscopic diamond particles on the tip so it bites into the screw recess, which cuts cam-out and the feed pressure needed to hold the bit in place. Behind each tip a BiTorsion zone absorbs peak loads instead of passing them to the tip. Everything sits in a Bit-Check case. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
These are not impact-driver bits — BiTorsion is a torsion zone for peak loads, not an impact rating. The set is bits only: no nutsetters, no sockets and no adapter to 3/8 inch. Profile coverage is PH, PZ, TORX and slotted only — there are no hex, square, TORX PLUS, tamper-resistant or PlusMinus bits. TORX runs TX 10, 15, 20, 25, 30 and 40, with no TX 6 to TX 9 and no TX 27. Nothing is insulated. The diamond grit is aggressive and will mark soft, plated or decorative screw heads.
Best For
✓ Drywall, decking and repetitive driving
✓ Machine-screw assembly work
✓ Site kits where cam-out wastes time
✓ Restocking worn PH 2 and PZ 2 bits
Key Features
Diamond-Coated BDC Tips
Microscopic diamond particles are bonded to the tip so it grips the inside of the screw recess. Less cam-out means less damage to the screw head, less feed pressure on your arm and fewer ruined fixings.
BiTorsion Zone Behind the Tip
A torsion zone absorbs load peaks that would otherwise reach the tip, which is where bits break. It is the reason a Wera BiTorsion bit outlasts a plain hardened bit on the same screw.
Weighted Towards the Sizes You Use
Four PH 2 and four PZ 2, two each of PH 1, PZ 1, TX 10 and TX 15, three each of TX 20 and TX 25. The set is stocked the way a working box empties, not one of each for a neat photo.
Rapidaptor Universal Holder
A 889/4/1 K holder, 1/4 inch x 50 mm, with magnetic retention and a one-handed tool-free bit change — supplied as part of the thirty, so the set works straight out of the case with a drill or a driver.

Frequently Asked Questions
Singular Expert Insight
The interesting part of this set is not the count, it is the distribution. Four PH 2, four PZ 2 and three each of TX 20 and TX 25 mean it is stocked the way a working bit box actually empties, so it stays useful for months instead of leaving you with a case full of PH 3 and one dead PZ 2. The diamond coating is a genuine difference on soft or painted heads, with one caveat worth knowing: the grit that stops cam-out also marks decorative screws, so keep a plain bit for visible fixings.

Buyer’s Guide
Buy it if
You drive a lot of Phillips, Pozidriv and TORX screws and want diamond-coated bits stocked in the quantities that actually run out, holder included.
Skip it if
You need impact-rated bits, hex or square profiles, or a small set — thirty bits is a restock, not a pocket kit.
Also consider
A Wera Bit-Safe assortment if you want hex and TORX PLUS coverage too, or the Kraftform Kompakt 20 RA-R (05051514001) for a ratcheting driver with a bit magazine.
