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

Does the bit holder count as one of the thirty?
Yes. Twenty-nine bits plus the 889/4/1 K Rapidaptor holder make thirty. The plastic Bit-Check case is supplied in addition and is not counted.
What does the diamond coating actually do?
Diamond particles bonded to the tip raise friction inside the screw recess, so the bit bites rather than slips. In practice that means less cam-out, less pressure needed on the driver and cleaner screw heads.
Can I use these in an impact driver?
No. BiTorsion absorbs load peaks in hand and drill driving; it is not an impact rating. Impact work needs bits specifically rated for it.
Are there any hex or square bits?
No. The set covers Phillips, Pozidriv, TORX and slotted only. If you need hex or Robertson, look at a Bit-Check with a wider profile mix or a bit assortment such as the Bit-Safe range.
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. Browse our Cable Tools - Testers category for more Wera bits and sets, or the wider Cables range for related workshop supplies.

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.
